Definitions

  • the invention relates to a siphon device, in particular for a wash basin in the sanitary area, with a tubular connecting part which can be connected to the wash basin and a deflecting part connected to the connecting part, by means of which a liquid flowing through the siphon device can be collected in order to form an odor trap.
  • Such a siphon device comprises several interconnected pipes with a circular cross-section.
  • a connecting pipe arranged approximately vertically, is connected to a washing area and usually extends downwards more than 20 cm from the washing area. This is followed by a first bend for diverting a liquid flowing through the siphon device by approximately 180° upwards towards the washing area and a second bend for diverting the liquid by approximately 90° towards a wall.
  • an overflow device for the washing area and a lifting rod for a valve device for accumulating the liquid in the washing area are also connected to the siphon device. This can lead to the spread of unpleasant odors. While strong cleaning agents can mask unpleasant odors, the often difficult-to-access source of bacteria often remains.
  • siphon devices become dirty relatively quickly because dirt often gets stuck and remains in the siphon device. Cleaning the siphon device up to the level of the sealing liquid in the siphon is possible without dismantling the entire Due to their design and dimensions, drawers below the washbasin, such as a vanity unit, require a drawer cutout, which usually significantly reduces the drawer's storage space.
  • Other siphon devices are available, for example, from DE 201 00 826 U1 , DE 20 2014 007392 U1 and DE 10 2009 043 859 A1 known.
  • the invention is based on the object of creating a siphon device that is easier to handle.
  • the siphon device has a tubular connecting piece that can be connected to the wash basin and a diverting piece connected to the connecting piece.
  • the diverting piece allows liquid flowing through the siphon device to be collected to form an odor trap.
  • the connecting piece and diverting piece are designed such that the flow velocity in the diverting piece is higher than that in the connecting piece.
  • a higher flow velocity in the diverting piece promotes self-cleaning effects, so that dirt particles are less likely to accumulate on the inner walls of the siphon device. By increasing the flow velocity, dirt particles located in the connecting piece are more easily sucked in and transported away by the diverting piece.
  • the ratio of the flow cross-section of the connecting part to the flow cross-section of the deflection part is between 5:1 and 1.5:1, preferably between 4:1 and 2:1, particularly preferably 3:1.
  • a reduction in cross-section therefore simply leads to an increase in the velocity of the liquid flowing through the siphon device in the area of the deflection part, so that dirt particles are less likely to deposit on the interior walls.
  • the siphon device according to the invention is easier to handle.
  • the aforementioned ratios of the flow cross-sections to one another also promote the throughput required in practice by modern siphon devices. This further development is based on the finding that self-cleaning of pipelines is achieved in a siphon device, particularly when a flow velocity of approximately 0.7 m/s is present periodically.
  • the previously described increase in flow velocity can be achieved particularly easily by having the connecting part with a circular flow cross-section and the deflecting part with a flow channel with a cross-sectional area in the shape of an elongated hole, whereby the diameter of the circular cross-sectional area of the connecting part corresponds to the length of the elongated hole of the flow channel.
  • This largely eliminates protrusions, recesses, edges, or gussets in the flow cross-section, all of which promote the accumulation of dirt. Dirt particles are therefore less likely to become trapped and remain; moreover, cleaning is easier due to the continuous transitions.
  • the deflection part opens into the connecting part at an angle of approximately 90°. Due to the 90° deflection in the area between the connecting part and the deflection part, the flow velocity at the edge is usually increased, which can promote the removal of dirt particles and largely prevent them from accumulating on the inner wall. The aforementioned abrupt change in flow direction can also help reduce the accumulation of dirt in parts of the siphon device.
  • the flow channel of the deflection part has, in the region of its junction with the connecting part, a rounded upper side which merges into the flow cross-section of the connecting part, wherein
  • the radius of the rounded upper surface of the flow channel of the deflection part corresponds to that of another deflection in the flow channel of the deflection part.
  • the rounded upper surface allows the flow cross-section for the fluid flowing from the connecting part into the deflection part to be largely continuously reduced. This can promote the occurrence of suction effects.
  • the radius of each inner curve of the flow channel of the deflection part corresponds approximately to the height of the flow channel of the deflection part
  • the radius of each outer curve of the flow channel of the deflection part corresponds approximately to twice the height of the flow channel of the deflection part, as will be explained below.
  • the deflection part has a drain pipe at its end opposite the connecting part with a diameter that approximately corresponds to the length of the elongated hole in the flow channel of the deflection part.
  • This refinement can also contribute to a laminar fluid flow through the siphon device and thus to high drainage performance.
  • the longitudinal axes of the drain pipe and the deflection part form an angle of approximately 120°, and the drain pipe, with its entire cross-sectional area below the further deflection, opens into the flow channel of the deflection part.
  • the cross-sectional expansion occurs exclusively in height. This means that the connecting pipe remains ventilated, so that no suction effect, for example, on the Sealing fluid can form in the siphon device if additional flushing is activated in a downpipe connected to the drain pipe.
  • the area at the upper curve of the tubular flow cross-section in the drain pipe is ventilated, largely preventing the formation of an air cushion.
  • the siphon device has a total height of approximately 80 mm with a barrier fluid height of approximately 50 mm.
  • This embodiment contributes to significantly simplified handling of the siphon device according to the invention. Firstly, the fluid travels very short distances in the siphon device. Should cleaning of the siphon device be necessary, only a few surfaces need to be cleaned. Secondly, the drawer cutout previously mentioned in relation to the prior art can be completely eliminated, so that the entire surface is available as a storage area for a drawer. This also has advantages in the manufacture and handling of cabinets installed beneath washbasins. Furthermore, such a siphon device can be easily accessed from underneath, which is a great relief for people who travel to the wash area in a wheelchair. Furthermore, such a siphon device is very easy to install.
  • siphon device can be constructed in one piece. It is clear that such a siphon device requires little material and can therefore be manufactured cost-effectively. Even parts that accidentally fall into the siphon device can be easily removed. Such a siphon device is also suitable for installation in wash areas such as showers and bathtubs.

  • the siphon device 1 according to Fig. 1 is in Fig. 2 in a schematic side view, in Fig. 3 in a schematic plan view and in Fig. 4 in a longitudinal section IV - IV according to Fig. 3 It should be noted that in all figures the hatching symbolizing a section has been omitted for the sake of simplicity and better clarity.
  • the siphon device 1 has a tubular connecting part 2 which can be connected to a washing area (not shown in detail) and a deflecting part 3 which is connected to the connecting part 2. With the aid of the deflecting part 3, a liquid 4 flowing through the siphon device 1, such as water, can be collected to form an odor trap (see Fig. 4 ).
  • Connecting part 2 and deflecting part 3 are designed such that the flow velocity in deflecting part 3 is higher than that in connecting part 2.
  • the ratio of the flow cross-section of the connecting part 2 to the flow cross-section of the deflecting part 3 is between 5:1 and 1.5:1, preferably between 4:1 and 2:1, particularly preferably 3:1.
  • the connecting part 2 has a flow cross-section with a circular cross-sectional area 5
  • the deflecting part 3 has a flow channel 6 with a cross-sectional area in the form of an elongated hole 7.
  • An elongated hole refers to an elongated bore. The narrow sides of the elongated hole are closed off by semicircles whose diameters correspond to the width of the elongated hole. The long sides of the elongated hole run parallel to one another.
  • the diameter 10 of the circular cross-sectional area 5 of the connecting part 2 corresponds to the length 11 of the slot 7 of the flow channel 6.
  • the flow channel 6 of the deflection part 3 has, in the region of its junction with the connecting part 2, a rounded upper side 12 which merges into the circular flow cross-section of the connecting part 2.
  • the radius 13 of the rounded upper side 12 of the flow channel 6 of the deflection part 3 corresponds to that of a further deflection 14. Furthermore, the radius 13 of the rounded upper side 12 corresponds to the radius of each inner curve 15, 16 of the flow channel 6 of the deflection part 3. The radius of each inner curve 15, 16 further corresponds approximately to the height 17 of the flow channel 6 of the deflection part 3. Furthermore, the radius 20 of each outer curve 21, 22 of the flow channel 6 of the deflection part 3 corresponds approximately to twice the height 17 of the flow channel 6 of the deflection part 3.
  • the deflection part 3 has a drain pipe 24 at its end 23 opposite the connection part 2.
  • the diameter 25 of the drain pipe 24 corresponds approximately to the length 11 of the slot 7 of the flow channel 6 of the deflection part 3, as shown in Fig. 3 is illustrated.
  • Fig. 2 shows that the longitudinal axes 26, 27 of the drain pipe 24 and the deflection part 3 enclose an angle 30 of approximately 120°.
  • Fig. 4 illustrates that the drain pipe 24 with its entire cross-sectional area opens into the flow channel 6 of the deflection part 3 just below the further deflection 14.

  • the Fig. 5 The siphon device 1 shown has an inner curve 15, which merges directly into the outer curve 22 of the further deflection 14. This allows the siphon device to be Fig. 5 shown embodiment has a shorter overall length than that shown in the Fig. 1 to 4 shown embodiment.
  • FIG. 6 Another embodiment of the siphon device is shown in Fig. 6 shown schematically in longitudinal section.
  • the rounding in the transition area between the connecting part 2 and the deflection part 3 is omitted.
  • FIG. 7 A fourth embodiment of the siphon device 1 is shown in the Fig. 7 to 9 shown, where Fig. 7 a schematic perspective view, Fig. 8 a schematic plan view of the siphon device according to Fig. 7 and Fig. 9 a schematic longitudinal section IX - IX in Fig. 8 show.
  • the embodiment of the siphon device 1 shown has a housing 33 that encloses all parts of the siphon device except the drain pipe. This creates a compact external appearance of the siphon device with an exclusive design.
  • the housing 33 is now omitted. Otherwise, the latter embodiment corresponds to that shown in the Fig. 1 to 4
