Definitions

  • the invention relates to a siphon device, in particular for a washing area in the sanitary area, according to the preamble of claim 1.
  • Such a siphon device is known from practice.
  • This siphon device has several interconnected pipes with a circular cross-section, with a connection pipe, arranged approximately vertically, being connected to a washing area, usually extending more than 20 cm downwards away from the washing area, whereupon a first bend extends for deflecting one through the siphon device connecting the flowing liquid by about 180 ° upwards towards the washing area and a second bend for deflecting the liquid by about 90 ° towards a wall.
  • an overflow device of the washing area and a lifting rod for a valve device for damming up the liquid in the washing area are also connected to the siphon device. This can lead to the spread of unpleasant smells.
  • the invention is based on the object of creating a siphon device which is easier to handle.
  • the siphon device has a tubular connector that can be connected to the washing area and a deflector that is connected to the connector. With the help of the deflection part, a liquid flowing through the siphon device can be accumulated in order to form an odor trap.
  • the connection part and deflection part are designed in such a way that the flow velocity in the deflection part is higher than that in the connection part. A higher flow speed in the deflection part favors self-cleaning effects, so that dirt particles are less likely to accumulate on the inner walls of the siphon device. Due to the increase in the flow speed, dirt particles located in the connection part are more easily sucked in and transported away through the deflection part.
  • the ratio of the flow cross-section of the connecting part to the flow cross-section of the deflecting part is advantageously between 5: 1 and 1.5: 1, preferably between 4: 1 and 2: 1, particularly preferably 3: 1.
  • This development is based on the Bernoulli principle, according to which the Pressure exerted by a liquid is inversely proportional to its flow rate and which Sum of velocity and pressure in flowing liquids is constant.
  • a cross-section reduction thus leads in a simple manner in the area of the deflecting part to an increase in speed for the liquid flowing through the siphon device, so that dirt particles can be less easily deposited on the inner walls. In this respect, too, the siphon device according to the invention is easier to handle.
  • connection part has a flow cross-section with a circular cross-sectional area and the deflection part has a flow channel with a cross-sectional area in the form of an elongated hole, the diameter of the circular cross-sectional area of the connection part being approximately the length of the elongated hole Corresponds to flow channel.
  • projections, recesses, edges or gussets in the flow cross section all of which favor the accumulation of dirt, can largely be avoided. Dirt particles are therefore less likely to get stuck and get stuck; cleaning is also easier due to the continuous transitions.
  • the deflecting part advantageously 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 deflecting part, the flow speed is usually increased at the edge, which promotes the removal of dirt particles and can largely prevent the particles from accumulating on the inner wall. The abovementioned abrupt change in the direction of flow can also help to reduce the accumulation of dirt in parts of the siphon device.
  • the flow channel of the deflecting part has a rounded top side merging into the flow cross-section of the connecting part in the area of its confluence with the connection part, wherein preferably the radius of the rounded upper side of the flow channel of the deflecting part corresponds to that of a further deflection in the flow channel of the deflecting part. Due to the rounded upper side, the flow cross section for the liquid flowing from the connection part into the deflection part can be largely continuously reduced. This can promote the occurrence of suction effects.
  • the radius of each inner rounding of the flow channel of the deflecting part corresponds approximately to the height of the flow channel of the deflecting part and the radius of each outer rounding of the flow channel of the deflecting part corresponds to about twice the height of the flow channel of the deflecting part, as will be explained below.
  • the deflecting part has a drain pipe with a diameter which corresponds approximately to the length of the elongated hole of the flow channel of the deflecting part.
  • the transition from the elongated hole flow cross-section of the deflecting part to the circular flow cross-section of the drain pipe can thus also be formed without projections, recesses, edges, gussets or the like and thus continuously. This development can also contribute to a laminar flow of liquid through the siphon device and thus to high drainage rates.
  • the longitudinal axes of the discharge pipe and deflection part enclose an angle of approximately 120 ° and the discharge pipe with its entire cross-sectional area opens into the flow channel of the deflection part below the further deflection.
  • the cross-section is only enlarged in height.
  • the connection pipe remains ventilated, so that no suction, for example on the Sealing liquid can arise in the siphon device if further flushes are actuated in a downpipe to which the drainage pipe is connected. If the liquid is not flowing, the area on the upper curve of the tubular flow cross-section in the drainage pipe is ventilated, so that the formation of an air cushion is largely prevented.
  • the siphon device has an overall height of approximately 80 mm with a barrier liquid height of approximately 50 mm.
  • This development contributes to a significantly simplified handling of the siphon device according to the invention.
  • the liquid in the siphon device thus covers very short distances. Should it be necessary to clean the siphon device, only a few surfaces need to be cleaned.
  • the drawer cutout previously mentioned in relation to the prior art can be completely omitted, so that the entire area is available as a storage area for a drawer.
  • This also has advantages in the manufacture and handling of cabinets attached below washbasins. Furthermore, such a siphon device can easily be driven under, which is a great relief for people who drive to the washing area in a wheelchair.
  • Such a siphon device can be installed very easily. Ultimately, the entire siphon device can be designed in one piece. It is clear that such a siphon device has a low material consumption and can therefore also be produced inexpensively. Even parts that accidentally fall into the siphon device can be removed from it again without great effort. Such a siphon device is also suitable for attachment to washing areas, such as showers and bathtubs.
  • a first embodiment of a siphon device 1 is shown schematically in a perspective view.
  • the siphon device 1 is particularly suitable for a washing area, such as a washstand, a shower or a bathtub, in the sanitary area.
  • a washing area such as a washstand, a shower or a bathtub
  • it can also be used, for example, in a sink in a kitchen and wherever a liquid can run off from a container with the formation of an odor trap.
  • 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 shown. It is pointed out that the hatching symbolizing a section has been omitted in all figures for the sake of simplicity and better clarity.
  • the siphon device 1 has a tubular connection part 2 that can be connected to a washing area (not shown in detail) and a deflection part 3 connected to the connection part 2. With the help of the deflection part 3, a liquid 4 flowing through the siphon device 1, such as water, can be accumulated in order to form an odor trap (please refer Fig. 4 ).
  • Connection part 2 and deflection part 3 are designed in such a way that the flow velocity in deflection part 3 is higher than that in connection part 2.
  • the ratio of the flow cross-section of the connection part 2 to the flow cross-section of the deflection part 3 is between 5: 1 and 1.5: 1, preferably between 4: 1 and 2: 1, particularly preferably 3: 1 2 has a flow cross-section with a circular cross-sectional area 5 and 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 denotes an elongated bore. The narrow sides of the elongated hole are closed by semicircles, the diameter of which corresponds to the width of the elongated hole. The long sides of the elongated hole run parallel to each other.
  • the diameter 10 of the circular cross-sectional area 5 of the connection part 2 corresponds approximately to the length 11 of the elongated hole 7 of the flow channel 6 Fig. 4
  • the flow channel 6 of the deflecting part 3 has a rounded upper side 12 merging into the circular flow cross section of the connecting part 2 in the region of its confluence with the connection part 2.
  • the radius 13 of the rounded upper side 12 of the flow channel 6 of the deflecting 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 rounding 15, 16 of the flow channel 6 of the deflecting part 3. The radius of each inner rounding 15 , 16 also corresponds approximately to the height 17 of the flow channel 6 of the deflecting part 3. In addition, the radius 20 of each outer rounding 21, 22 of the flow channel 6 of the deflecting part 3 corresponds to about twice the height 17 of the flow channel 6 of the deflecting part 3.
  • the deflection part 3 has a discharge pipe 24 at its end 23 opposite the connection part 2.
  • the diameter 25 of the discharge pipe 24 corresponds approximately to the length 11 of the elongated hole 7 of the flow channel 6 of the deflecting part 3, as shown in FIG Fig. 3 is illustrated.
  • Fig. 2 shows that the longitudinal axes 26, 27 of the drain pipe 24 and deflection part 3 enclose an angle 30 of approximately 120 °.
  • Fig. 4 shows that the entire cross-sectional area of the outflow pipe 24 opens into the flow channel 6 of the deflection part 3 just below the further deflector 14.
  • the siphon device 1 has a total construction height 31 of about 80 mm with a barrier liquid height 32 of about 50 mm (see Fig. 4 ).
  • the siphon device can be used in particular in combination with a valve device with an overflow valve integrated into the valve device. In this case, as in the Figs. 1 to 9 shown, a lifting linkage, not shown in detail and described in relation to the prior art, is completely omitted.
  • the siphon device 1 shown has an inner rounding 15 which merges directly into the outer rounding 22 of the further deflection 14.
  • the siphon device according to the in Fig. 5 embodiment shown has a shorter overall length than that in the Figs. 1 to 4 Have shown embodiment.
  • FIG Fig. 6 Another embodiment of the siphon device is shown in FIG Fig. 6 shown schematically in longitudinal section.
  • the rounding in the transition area between the connecting part 2 and the deflecting part 3 is omitted.
  • FIG. 7 a schematic perspective view
  • Fig. 8 a schematic plan view of the siphon device according to FIGS. 7 and 9 a schematic longitudinal section IX - IX in Fig. 8 demonstrate.
  • the embodiment shown of the siphon device 1 has a housing 33 which surrounds all parts of the siphon device except for the drain pipe. This creates a compact external appearance of the siphon device in an exclusive design.
  • the height 17 of the elongated hole 7 of the flow channel 6 can be, for example, 13.5 mm, the length 11 of the elongated hole is preferably 37 mm.
  • the diameter 10 of the circular cross-sectional area of the connection part 2 and the diameter 25 of the drain pipe 24 can also be approximately 37 mm.
  • the entire siphon device 1 is made in one piece.
  • An ideal flow behavior results in particular in the drainage pipe when the flow cross section there is approximately half filled with liquid and the space above the liquid is ventilated, as has been explained above.
