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 to shield odor and noise nuisance from the sewer system from the inside.
- a residual water is usually maintained in the siphon, which acts like a closure so that no air from the sewer system can penetrate into 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 costly 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 unpleasant to do or very harmful to the environment, since the cleaning agents get into the wastewater and are laboriously removed there again.
- the object is achieved by a siphon according to claim 1 independent.
- 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 tion cross-sectional area, 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 line connects the inlet opening and from the outlet opening and a transition between the inlet opening and siphon line 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 residual water in the siphon section, so that no odors 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 inlet opening may be provided with a privacy screen through a cover or the like.
- 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 which creates water pressure on the siphon section.
- the siphon cross-sectional extension and the siphon cross-sectional longitudinal extension are constant over 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-section 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 adjoins the constant silicon line.
- the siphon section can include 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 of 2 to 4, preferably 2.3 to 3, in particular particularly 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 special 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 to run off without any obstacles, so that no backwater is created and the speed of the water is not reduced when it drains because the water has to eat through a small opening fH.
- 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 speed.
- the transition from the inlet opening to the siphon section is arranged acentrically from a central axis of the inlet opening 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 optimally flow 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 liq fluid 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 of direction in the direction of a central axis of the inlet opening arranged perpendicular to the inlet opening cross-section.
- the flow after the first direction change section can preferably be conducted against gravity and after the second direction change section can be conducted along gravity.
- the central axis is preferably aligned along the force of gravity.
- 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 against the fall line.
- Such a siphon section enables the water to be stopped in the first section of the change of direction and at the same time a very small design of the siphon. This is particularly important for 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 including a change in direction of preferably at least 180 °, particularly preferably at least 185 °, further preferably at least 190 °.
- At least one, preferably the first and the second, direction change section can have a radius of a center line of the transverse extent of the siphon cross section, which corresponds to the transverse extent of the siphon section substantially.
- 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 radius along the center line preferably corresponds along the entire area of the change in direction, in particular of the first and second change in direction sections, essentially to the transverse extent of the siphon section.
- the transition can be arranged in such a way that the liquid can flow vertically in a fall line at the transition in a position of use.
- the siphon is preferably optimized for the amount of water that is generally consumed when draining liquids. Since the cross-sectional area of the siphon is constant, a smaller difference in the flow velocity of the amount of water can be achieved along the fall line at the transition.
- the middle part can encompass 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 tightly with a screw, so that the private user cannot accidentally remove the cover to clean the siphon. This is especially true because the siphon does not require any cleaning.
- any inner surfaces of the siphon are preferably formed from a single cohesive surface which are only connected via their outer edge.
- 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. be given, which are designed to be removable, so that with the help of the rings, the mounting edge can be safely adjusted to a height and can be fixed at a height.
- 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.
