Definitions

  • the invention relates to a siphon for closing an outlet pipe, the siphon comprising a housing with an inflow opening arranged in a housing wall, an outflow opening arranged in a housing wall and a separating wall directed downward from above between the inflow opening and the outflow opening and having a passage opening, wherein the passage opening lies in a lower position than both the inflow opening and the outflow opening.
  • the separating wall forms two chambers in the housing which connect to each other via the passage opening in a low position.
  • water enters the housing via the inflow opening it will flow via these chambers to the outflow opening.
  • water When water is no longer being supplied, water will remain standing in the two chambers, whereby the passage between the inflow opening and the outflow opening is closed. This creates a water seal.
  • the level in the housing can however fall due to evaporation and eventually fall below the level of the passage opening, whereby an open connection once again occurs. In accordance with norms this height of the water seal must be 5 centimetres. Because the height of the passage opening, the inflow opening and the outflow opening is easily 1 to 2 centimetres, the minimal height of a siphon will be a minimum of 7 centimetres.
  • a siphon according to the preamble characterized in that a flexible wall part is provided adjacently of at least one opening.
  • the flexible wall part lengthens the wall parts of the siphon, such as the separating wall and the walls with the inflow opening and outflow opening. A greater water seal height is hereby obtained in the siphon.
  • the flexible wall part When water flows through the siphon the flexible wall part will bend aside, whereby the water can flow through unimpeded and the capacity of the siphon is not limited.
  • the flexible wall part When the water comes to rest, the flexible wall part will once again move to the rest position and thereby lengthen the associated wall.
  • the flexible wall part comprises a flexible flap arranged with an end on a first housing wall and lying with a free end against an opposite second housing wall.
  • the flexible flap provides an additional barrier to unobstructed passage between the inflow opening and the outflow opening.
  • the unidirectional seal still provides a closure which prevents stench flowing from the outflow opening via the housing to the inflow opening.
  • the flexible flap further ensures that part of the water evaporates less quickly, since a direct connection to the often warmer outside environment is closed.
  • the flexible flap also prevents unpleasant odours entering a user space, such as a bathroom, via the siphon when there is overpressure in the sewer.
  • a flexible flap such as a silicone flap, shapes itself easily to the wall against which the flap lies. If fouling were to adhere to the wall, the flexible flap will then still provide for a good seal. Nor will hairs get caught behind such a flexible flap, whereby blockage at this point is prevented. Leakage caused by hairs being left behind is also prevented.
  • a unidirectional seal is arranged in the passage opening.
  • the unidirectional seal is formed here by the flexible wall.
  • the effective height of the water seal which is usually defined by the height between the outflow opening and the passage opening, is thus greater as a result. This is because the height of the water seal is determined in the invention by the height between the outflow opening and the passage opening, including the height of the passage opening, i.e. the unidirectional seal.
  • the unidirectional seal is a flexible flap
  • the free end of the flexible flap is oriented in flow direction in the channel. Should water attempt to flow back, it will be prevented from doing so by the flexible flap. In addition, the water flowing back will press the free end oriented in flow direction against the wall of the channel, whereby a better seal is created.
  • the separating wall is formed at least partially by the unidirectional seal in the channel.
  • the flexible wall part can be arranged on a fixed wall, such as for instance the separating wall, although the flexible wall part can also form the whole wall in the siphon.
  • the unidirectional seal can further be arranged in the outflow opening and/or the inflow opening.
  • FIG. 1A shows a cross-sectional view of a first embodiment 1 of a siphon according to the invention.
  • Siphon 1 has a housing 2 with an inflow opening 3 and an outflow opening 4.
  • a separating wall 5 is directed downward in the housing from the upper side, thereby creating a first chamber 6 and a second chamber 7.
  • a passage opening 8 is situated under separating wall 5 in which a flexible flap 9 is arranged as flexible wall and unidirectional seal.
  • Figure 1C shows the situation where water flows via inflow opening 3 into housing 2. Flap 9 will be pressed open by the initially larger water column 10, whereby the water can flow away via outlet opening 4.
  • FIG. 2 shows a second embodiment 20 of the siphon according to the invention.
  • Siphon 20 has a housing 21 with an inflow opening 22 and an outflow opening 23.
  • An outlet pipe 29, which is provided with a sleeve, is connected to outflow opening 23.
  • a separating wall 24 is directed downward from the upper side, thereby forming a first chamber 25 and a second chamber 26.
  • a first flexible flap 27 is arranged in inflow opening 22 in the channel formed by first and second chambers 25, 26, and a second flexible flap 28 on the housing wall adjacently of outflow opening 23.
  • First flap 27 reduces the evaporation of water in first chamber 25, while second flap 28 increases the height of the water seal in that the length of the housing wall is hereby increased. Only when there is sufficient water pressure will flexible flap 28 be pressed open and the water can flow away.
  • the flexible flaps 27 and 28 ensure that the water in both chambers 25, 26 is closed off relative to outlet pipe 29 and the outside environment, whereby evaporation of the water in these two chambers 25, 26 is prevented to a considerable extent.
  • Figure 3 shows a cross-sectional view of a third embodiment 70 of a siphon according to the invention.
  • Siphon 70 has a housing 71 with an inflow opening 72, a passage opening 73 and an outflow opening 74.
  • a flexible closing flap 75 is arranged adjacently of passage opening 73 on separating wall 76.
  • An annular upright wall 77 forming an additional barrier in the water seal is arranged around the downward directed wall 76 and passage opening 73. It is here also the case that the height of siphon 70 can be smaller owing to the flexible closing flap 75.
  • Figure 4 shows a variant of the embodiment according to figure 3 .
  • a second flexible flap 78 is provided on the annular upright wall 77.
  • the water seal height is hereby increased further, or the overall height of housing 71 can be reduced while the water seal height remains the same.
