Definitions

  • the following application is directed to a siphon for a drain, in particular a shower siphon or wash basin siphon.
  • Siphons are usually installed in liquid drains in order to "screen off odor and noise nuisance from the sewer system in interiors.
  • a residual water is usually maintained in the siphon, which acts like a seal so that no air from the sewer system can penetrate the room.
  • Such siphons are provided with filter elements or inserts in order to free them from the siphon-clogging hair and similar small parts.
  • Such collection systems have the disadvantage that they have to be cleaned in a complex manner.
  • the inserts are either removed by hand or chemicals are poured down the drain, which can dissolve the small parts and hair. This work is either uncomfortable to do or very harmful to the environment, since the cleaning agents end up in the wastewater and have to be removed again there, which is time-consuming.
  • a siphon for a drain in particular a shower drain, which has an inlet opening with an inlet opening cross-section with an inlet opening cross-sectional area, comprises a siphon section with a siphon cross-section and a siphon cross-sectional area and a drain opening with a drain cross-section and a drain cross-sectional area.
  • Liquid can be introduced into the siphon through the inlet opening and removed from the siphon through the outlet opening.
  • the siphon section connects the inlet opening and the drain opening and a transition between the inlet opening and the siphon section is arranged in the siphon.
  • the cross-sectional area of the inlet opening is larger than the cross-sectional area of the siphon.
  • the cross-sectional expansion of the siphon over the siphon section is constant.
  • the siphon cross-sectional area is of course also constant over the siphon section.
  • Such a siphon leads to a high water velocity when flowing through the siphon, so that no foreign bodies get stuck in the siphon. At the same time, a biofilm is largely prevented. Despite the high speed, there is always a residue of water in the siphon section, so that no smells or noises can get through the sewer pipe through the siphon into the interior of the apartment.
  • the inlet opening is the largest opening in the siphon into which water can enter.
  • the lid opening is not the inlet opening, the inlet opening is the opening that can be filled with water.
  • protection for small parts such as a finger ring protection device, to the inlet opening, this protection having no influence on the cross-sectional area of the inlet opening.
  • the Inlet opening cross-sectional area is the area in which a water surface can arise and through which water pressure is created on the siphon section.
  • the siphon cross-sectional area is also constant over the siphon section.
  • the cross-sectional dimension of the siphon is the smallest dimension transverse to the direction of flow of the water in the siphon section.
  • the siphon cross-sectional longitudinal expansion is also perpendicular to the direction of flow in the siphon section perpendicular to the siphon cross-section.
  • the cross-sectional area of the drain is the smallest cross-sectional area of the drain that connects to the constant siphon section.
  • the siphon section can comprise two direction change sections.
  • the siphon cross-section can be an elongated hole, in particular an elongated hole with a ratio of longitudinal extent to transverse extent in a range from 2 to 4, preferably 2.3 to 3, in particular preferably 2.5 to 2.9.
  • the longitudinal extension corresponds to the longitudinal extension of the siphon cross-section and the transverse extension corresponds to the cross-sectional extension of the siphon.
  • Such a siphon cross-section leads to an optimal ratio of outflowing water and the size of the siphon, in particular the height of the siphon.
  • the cross-sectional area of the drain can be larger than the cross-sectional area of the siphon.
  • Such a design of the cross-sectional area of the drainage allows the water from the siphon line to drain freely, so that no backwater is created and the speed of the water is not reduced when it drains because the water has to flow through a small opening.
  • the inlet opening can be designed in the shape of a gap, preferably ring-shaped, in particular circular ring-shaped or a square or triangular gap, the gap in particular including a central part.
  • a slit-shaped inlet opening prevents large objects from entering and at the same time enables a sufficiently fast water drainage rate.
  • the transition from the inlet opening to the siphon section is arranged eccentrically from a central axis of the inlet opening which is arranged perpendicular to the inlet opening cross section.
  • the central axis is therefore arranged in the center of the circle.
  • the central axis is also arranged in the middle of the square or triangle.
  • the central axis is preferably arranged in the middle of the central part.
  • acentric means that the transition into the siphon section is not arranged in the middle of the siphon or on the central axis, but at a distance from the middle of the siphon.
  • the transition is consequently arranged at least partially below the gap, so that the water in the fall line can run directly into the siphon section.
  • the fall line corresponds to the direction of gravity when the siphon is used as intended.
  • a gradient towards the transition can be arranged within the inlet opening so that the water can flow optimally into the siphon section.
  • the gradient has its lowest point at the transition.
  • an edge of the inlet opening and siphon section can be rounded, in particular the edge can have a radius of essentially 5-7 mm, preferably 6 mm.
  • the transition reduces the cross-sectional area through which the liquid must flow to the siphon cross-sectional area. Due to the water pressure created by the water in the inlet opening, the water flows comparatively quickly into the siphon section at the transition.
  • Such a transition enables an optimal flow of the liquid and leads to as little turbulence as possible and thus a flow that is as laminar as possible.
  • the siphon section can be designed in such a way that the liquid, from the transition which, viewed from the inlet opening, represents an opening in the direction of fall, can be guided as a first change in direction in the direction of a central axis of the inlet opening arranged perpendicular to the inlet opening cross-section.
  • a first direction change section preferably leads to a change in direction in a central part of the siphon, the change in direction preferably being at least 180 °, particularly preferably at least 185 °, more preferably at least 190 °.
  • the liquid preferably flows in the fall line, and after the first direction change section, the direction of the liquid comprises at least a partial vector opposite to the fall line.
  • Such a siphon section enables the water to be held up in the first section of the change of direction and, at the same time, a very small construction of the siphon. This is particularly important in the case of built-in components flush with the floor.
  • a second direction change section of the siphon section can redirect the water in the direction of fall, the second direction change section comprising a change in direction of preferably at least 180 °, particularly preferably at least 185 °, more preferably at least 190 °.
  • At least one, preferably the first and the second, direction changing section can have a radius of a center line of the transverse extent of the siphon cross-section which essentially corresponds to the transverse extent of the siphon section.
  • the center line of the transverse extent is the center between the shortest connection of the siphon section side walls and the radius of this center line is preferably considered over a range of at least 150 °.
  • the transition can be arranged in such a way that the liquid can flow perpendicularly in a fall line at the transition.
  • the middle part can comprise the second direction change section, and in particular comprise a detachable cover element, so that access to the drain opening is possible without going through the direction change sections.
  • the detachable cover element therefore comprises a part of the second direction change section and thus enables access through the siphon access in the event of sewer cleaning work.
  • the cover element is preferably fastened by a special lock or, for example, screwed tight with a screw, so that the private user does not accidentally open the cover can dismantle to clean the siphon. This is especially true because the siphon does not require any cleaning.
  • no connecting elements are formed between the respective inner walls of the inlet opening, the siphon line and the drain opening.
  • Bars are elements that have a diameter of less than 20mm and are therefore so narrow that hairs wrap around them and do not simply flow off. Wider elements are not considered to be bars.
  • the inlet opening can be surrounded by a built-in edge, the built-in edge being designed to be height-adjustable, preferably designed to be height-adjustable by means of a thread.
  • the thread can in particular be surrounded by at least one, preferably three, rings which are designed to be removable, so that the mounting edge can be reliably adjusted to a height and fixed at a height with the aid of the rings.
  • the siphon can furthermore be designed in such a way that at least in the siphon section there is no section in which the direction of flow of the water meets a surface perpendicularly.
  • Figure 1 shows a section through a siphon 1 according to the invention.
  • the siphon 1 comprises an inlet opening 2 with an inlet opening cross-sectional extension 3 and an inlet opening cross-sectional area 3a (not shown).
  • the siphon 1 further comprises a siphon section 4 with a siphon cross-sectional extension 5 and a siphon cross-sectional area 5a (not shown).
  • the siphon 1 comprises a drain opening 6 with a drain cross-sectional extension 7 and a drain cross-sectional area 7a (not shown).
  • the siphon 1 is in particular a shower drain siphon or a wash basin siphon.
  • the inlet opening cross-sectional area 3a, the siphon cross-sectional area 5a and the drainage cross-sectional area 7a are each formed perpendicular to the drawing area, so that they are not explicitly shown.

  • the siphon section 4 has a siphon cross-section with a siphon cross-sectional dimension which is the smallest distance between the inner walls of the siphon section 4.
  • the inlet opening cross-sectional area 3a is larger than the siphon cross-sectional area 5a and the siphon cross-sectional extension 5 is constant over the siphon section 4.
  • the siphon section 4 has a first direction changing section 9 and a second direction changing section 10, each of which deflects the water flow by more than 180 °.
  • the second direction changing section 10 is arranged in the central part 11 and the first direction changing section 9 leads from the transition 8 to the central part 11.
  • the transition 8 is arranged eccentrically and is therefore not arranged on the central axis 12 of the siphon, and in particular not in the central part 11.
  • the siphon section 4 has a center line 13 which corresponds to the center point of the siphon cross-sectional extent 5.
  • the radius 9a, 10a of the direction change sections 9, 10 essentially corresponds to the siphon cross-sectional extension 5.
  • the drain opening 6 has a drain opening cross-sectional area 7a which is larger than the siphon cross-sectional area 5a.
  • the liquid flows from above into the inlet opening 2 and then essentially vertically into the siphon section 4.

  • the siphon cross-sectional expansion 5 is 14mm.
  • the longitudinal extension of the siphon cross-section is 40 mm.
