Description

[0001] The invention relates to a siphon for the sanitary sector, in particular a tube siphon or a cup siphon, comprising at least first components and second components, wherein the first components comprise a dip tube element and / or a wall tube element and the second components comprise a curved element or a cup element, according to the preamble of claim 1.

[0002] A siphon is designed to convey a medium, particularly wastewater, from a sink or basin into a wall connection. It creates a gas or odor trap because the medium remains in the curved element or cup element. A siphon with a curved element forms a tubular siphon, and a siphon with a cup element forms a cup siphon.

[0003] A generic siphon is known from DE 87 04 429.3. Therein, a cup siphon is disclosed, of which all parts, ie, the first components and the second components, are made of the same material, namely the same metal or the same plastic.

[0004] Another siphon is described in DE 20 2013 007 856 U1 as a tubular or cup siphon. All the first components are made of a polymer, specifically chrome-plated ABS (acrylonitrile butadiene styrene).

[0005] The disadvantage of using plastics for the first components is that they can be attacked and deteriorated by the effects of aggressive media contained in wastewater, such as cleaning agents or active substances. A disadvantage of using the same metal for the first components can be complex processing, for example, adjusting the length of the first components to suit the specific installation situation.

[0006] The object of the invention is to provide a siphon which is, on the one hand, robust against aggressive media and, on the other hand, can be manufactured and installed with little effort.

[0007] This problem is solved by the features of claim 1. Disclosure of the invention

[0008] The invention discloses a siphon, in particular a tubular siphon or a cup siphon comprising at least first components and second components, wherein a) the first components are a dip tube element and / or a wall tube element, and b) the second components comprise an arc element or a cup element

[0009] The immersion pipe element is designed and intended to connect the siphon to a sink or washbasin and, when the siphon is in use, has a substantially vertical orientation. The wall pipe element is designed and intended to connect the siphon to a wall connection and, when the siphon is in use, has a substantially horizontal orientation. The curved element and the cup element are designed and intended to accommodate a certain volume of the medium, thereby creating a gas or odor seal.

[0010] According to the invention, it is provided that a) at least one first component consists of brass, in particular of chrome-plated brass, and b) the second components are made of stainless steel, in particular chrome-plated stainless steel.

[0011] Brass is an alloy of copper and zinc to which other elements such as aluminum, iron or nickel are added as required.

[0012] Stainless steel is an alloyed or unalloyed steel that contains at least 10.5% chromium and less than 1.2% carbon.

[0013] Because at least a first component, namely the immersion tube element and / or the wall tube element, is made of brass, which is easily machined, it is possible to easily cut the at least one component to a desired length, in particular by sawing.

[0014] On the other hand, because the second components, the curved element in a tubular siphon and the cup element in a cup siphon, are made of stainless steel, in particular chrome-plated stainless steel, there is a high resistance to aggressive cleaning agents and active substances, especially in the place where the medium is standing for a certain period of time.

[0015] The siphon according to the invention thus advantageously combines simple manufacture and assembly with high resistance to aggressive media.

[0016] According to a preferred embodiment of the siphon, a first component of the first components can be made of brass, and another first component of the first components can be made of stainless steel. In particular, the wall tube element can be made of brass, and the immersion tube element can be made of stainless steel.

[0017] In a further development, the siphon can additionally have third components which comprise at least one union nut which is designed and provided for a detachable connection of first components and second components, wherein the at least one union nut is preferably made of die-cast zinc or brass.

[0018] A thread cooperating with the union nut can be formed at one end of the first component or the second component.

[0019] For example, a first union nut may be provided for a first detachable connection between the dip tube element and the bend element or the cup element and a second union nut may be provided for a second detachable connection between the bend element or the cup element and the wall tube element.

[0020] Furthermore, a sealing element can be arranged between the union nut and the first component or the second component in order to seal the connection.

[0021] According to a preferred embodiment, the brass may contain between 63.1 and 68.5% copper (Cu), 0.03 percent lead (Pb), 0.05 percent iron (Fe) and 0.25% nickel (Ni) and zinc (Zn).

[0022] The stainless steel can also be formed by an alloyed or unalloyed steel which contains at least 10.5% chromium and less than 1.2% carbon.

[0023] Particularly preferably, the stainless steel may contain 0.073 percent carbon (C), 0.420 percent silicon (Si), 1.250 percent manganese (Mn), 0.030 percent phosphorus (P), 0.001 percent sulfur (S), 18.51 percent chromium (Cr) and 8.010 percent nickel (Ni).

[0024] Furthermore, it can be provided that the siphon includes a wall rosette which encloses the wall pipe element. drawing
