Description

The invention relates to a siphon for sanitary applications, in particular a pipe 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 pipe element and the second components comprise a bend element or a cup element, according to the preamble of claim 1. A siphon is designed to carry a medium, especially wastewater, from a sink or basin into a wall connection and forms a gas or odor seal because the medium remains in the elbow or cup element. A siphon with an elbow element is called a tubular siphon, and a siphon with a cup element is called a cup siphon. A siphon of this type is known from DE 87 04 429 . 3. There, a cup siphon is disclosed in which all parts, i.e., the first components and the second components, are made of the same material, namely the same metal or the same plastic. Another siphon is described in DE 20 2013 007 856 U1 as a tubular or cup siphon. There, all the first components consist of a polymer, in particular chrome-plated ABS (acrylonitrile butadiene styrene). A disadvantage of using plastics for the initial components is that they can be attacked and degrade by aggressive media such as cleaning agents or active substances contained in the wastewater. A disadvantage of using the same metal for the initial components can be the need for complex processing, e.g., adjusting the length of the initial components to the specific installation situation. The object of the invention is therefore to provide a siphon that is robust against aggressive media on the one hand and can be manufactured and assembled with little effort on the other. This problem is solved by the features of claim 1. Disclosure of the invention 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 comprise a dip tube element and / or a wall tube element, and b) the second components comprise an arc element or a cup element. The dip tube element is designed and intended to connect the siphon to a sink or basin and has a substantially vertical orientation when the siphon is in use. The wall pipe element is designed and intended to connect the siphon to a wall connection and has a substantially horizontal orientation when the siphon is in use. The elbow element and the cup element are designed and intended to hold a certain volume of the medium in order to create a gas or odor seal. 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 consist of stainless steel, in particular of chrome-plated stainless steel. Brass is an alloy of copper and zinc, to which other elements such as aluminum, iron or nickel are added as needed. Stainless steel is understood to be an alloyed or unalloyed steel which contains at least 10.5% chromium and less than 1.2% carbon. Because at least one first component, namely the immersion tube element and / or the wall tube element, is made of brass, which is easily machinable, it is possible to simply cut the at least one component to a desired length, especially by sawing. On the other hand, because the second components, the arc element in a tubular siphon and the cup element in a cup siphon, are made of stainless steel, especially chrome-plated stainless steel, there is a high resistance to aggressive cleaning agents and active substances precisely where the medium stands for a certain period of time. The siphon according to the invention thus advantageously combines simple manufacturing and assembly with high resistance to aggressive media. According to a preferred embodiment of the siphon, one component of the first set of components can be made of brass and another component of the first set of components can be made of stainless steel. In particular, the wall pipe element can be made of brass and the immersion pipe element can be made of stainless steel. The first components, especially all the first components, can also be made of brass, particularly chrome-plated brass. In addition, the siphon can have third components comprising at least one union nut designed and provided for a detachable connection between first and second components, wherein the at least one union nut is preferably made of die-cast zinc or brass. A thread that interacts with the union nut can be formed at one end of the first component or the second component. For example, a first union nut may be provided for a first detachable connection between the immersion tube element and the elbow element or the cup element, and a second union nut may be provided for a second detachable connection between the elbow element or the cup element and the wall tube element. Furthermore, a sealing element can be placed between the union nut and the first component or the second component to seal the connection. According to a preferred embodiment, the brass may contain between 63.1 and 68.5% copper (Cu), 0.03% lead (Pb), 0.05% iron (Fe) and 0.25% nickel (Ni) and zinc (Zn). Stainless steel can also be formed from an alloyed or unalloyed steel containing at least 10.5% chromium and less than 1.2% carbon. Particularly preferred, 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). Furthermore, it may be provided that the siphon includes a wall rosette which encompasses the wall pipe element. drawing Exemplary embodiments of the invention are explained in more detail in the following description with reference to the figures. The figures show: Fig. 1 a side view of a tubular siphon as a first embodiment of the invention; Fig. 2 an exploded view of the tubular siphon of Fig. 1; Fig. 3 a side view of a cup siphon as a second embodiment of the invention; Fig. 4 an exploded view of the cup siphon of Fig. 1. Description of the exemplary implementations The siphon 10 shown in Fig. 1 and Fig. 2 is intended for use in sanitary areas and is designed, for example, as a tubular siphon 10a for a washbasin or sink. The tubular siphon 10a comprises a wall pipe element 1, an elbow element 2, and a dip tube element 3. These components come into contact with liquids, such as aggressive water, cleaning agents, and detergents. During operation of the tubular siphon 10a, liquid remains in the elbow element 2, preventing odors from escaping. The immersion tube element 3 and the wall tube element 1 belong to the first components of the tube siphon 10a and the arc element 2 forms a second component of the tube siphon 10a. The wall pipe element 1 and the immersion pipe element 3 are preferably both made of brass. According to a further embodiment, only one of these components 1, 3 can be made of brass and the other first component 3, 1 of stainless steel.
