Definitions

  • the invention relates to a valve device, in particular for a washing area in the sanitary area, according to the preamble of claim 1.
  • valve body can be moved, for example via a lever linkage, from its position for releasing a flow (release position) through a connector attached to the washing area into its position for blocking such a flow (blocking position) and vice versa.
  • the valve body is elongated and its lower section rests on a part of the lifting rod that projects into the drain.
  • This part of the lifting rod is usually located in a vertical pipeline below the connection part, which connects the connection part with a downstream siphon.
  • the lifting linkage further comprises a part which is guided, for example, to a mixer tap at the washing area and which can be moved up and down manually in order to thereby move the valve body into its release position or blocking position.
  • valve device On the one hand, such a valve device is of relatively complicated construction. On the other hand, practice shows that such devices get dirty relatively quickly and have to be cleaned regularly and at great expense.
  • the invention is based on the object of creating a valve device which is more simply constructed and easier to handle, and in particular is less prone to contamination.
  • the valve device has a connection part with which it is usually attached to a drain of the washing area.
  • the valve device also has a valve body which is designed to enable or block a flow through the connecting part.
  • the connection part is set up, for example, as a drain part.
  • the connection part has a fixed device by means of which the valve body is held in its position for releasing the flow (release position).
  • the invention is therefore based on the idea of completely dispensing with the movable lifting linkage mentioned above in relation to the prior art. On the one hand, this simplifies the construction and manufacture of the valve device and the washing area as a whole; on the other hand, the valve device according to the invention is easier to handle.
  • the valve body can also be made significantly shorter in terms of its overall length, which also facilitates its handling and cleaning and leads to lower manufacturing costs.
  • the connection part in the sense of a double effect ultimately not only serves to fasten the valve device to the washing area but also to hold the valve body in its release position by means of the fixed device.
  • the stationary device is at least one projection provided on the connection part, the valve body preferably at least partially protruding into the connection part and the at least one projection being arranged on a tubular inner wall of the connection part.
  • a projection can preferably be provided in one piece and therefore with little effort on the connection part, which contributes to a simple construction of the valve device.
  • the lever linkage in which a part almost completely penetrates the cross-section of a subsequent pipeline, such a projection narrows the cross-section of the connection part and thus the drain cross-section only slightly.
  • such a valve device is therefore less likely to get dirty than a conventional valve device.
  • valve body sits in its release position on the stationary device, preferably on the at least one projection.
  • a seating of the valve body on a part of the connection part can be implemented in a relatively simple manner and thus inexpensively, as will be explained in more detail below.
  • connection part and the valve body are connected to one another such that they can move relative to one another, the valve body having at least one groove on its outer circumference for receiving the at least one projection and the at least one groove preferably being designed and arranged in such a way that the valve body moves from its position to Blocking the flow (blocking position) can be moved into its release position and vice versa by means of a preferably counterclockwise rotary movement.
  • a projection / groove arrangement therefore corresponds to a tongue / groove connection known from wood interior construction, with the difference that the valve body is designed to be movable relative to the connection part when the at least one groove of the valve body is along the at least one projection of the connection part emotional.
  • Such at least one groove can be provided on the valve body with little effort.
  • a rotary movement for transferring the valve body from its blocking position into its release position can be achieved in a structurally simple manner.
  • the at least one groove has a first section for raising / lowering the valve body and a second section adjoining the first section with which the valve body rests on the at least one projection and is thereby held in its release position.
  • the at least one groove with its two sections serves on the one hand to transfer the valve body from its locking position to its release position and vice versa, and on the other hand, in the sense of a double effect, also to hold the valve body in its release position.
  • the valve body is advantageously raised / lowered by means of a manually executable rotary movement of the valve body.
  • a rotary movement can be carried out quickly and with little effort, it does not require any special instructions and can also be carried out easily and without problems by children and old people.
  • the at least one projection has a rounded upper side and the second section of the at least one groove has a corresponding lower side.
  • the rounding of the top of the at least one projection ensures that on the one hand it opposes the flowing liquid only with a low flow resistance, on the other hand it is ensured that, for example, hair does not get stuck on the at least one projection but is transported further by the liquid towards the siphon. This further reduces the risk of contamination of the valve device according to the invention.
  • the valve body has an overflow valve which, in the blocking position of the valve body, automatically moves from its closed position, which seals the valve body, to its open position, and vice versa, when a maximum fill level of a liquid in the washing area is exceeded.
  • the valve device according to the invention can also be used as a so-called overflow device, with no overflow devices at the washing area, such as overflow openings and flow connections between each Overflow opening and a drain are to be provided. This also reduces the manufacturing effort for the washing area.
  • the valve device according to the invention thus serves in the sense of a double effect not only to release or block a drain for the washing area but also as an overflow device, so that overflow of the washing area and thus flooding of a bathroom, for example, is effectively prevented.
  • the overflow valve can be moved from its closed to its open position and vice versa by the forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight.
  • the level of the hydrostatic pressure in relation to the counteracting buoyancy is therefore the trigger for moving the overflow valve from its closed to its open position or to leave it in its closed position. It follows that the liquid in the washing area monitors itself to a certain extent. If the hydrostatic pressure rises above a threshold value, it pushes the overflow valve against the buoyancy from its closed to its open position. As long as the hydrostatic pressure is below the threshold value, the overflow valve remains in its closed position. With the aid of the valve device having an overflow valve, the aforementioned operating principle can be implemented very simply and thus inexpensively.
  • the overflow valve is advantageously in the release position of the valve body in its closed position. It follows that the valve body is used to drain liquid in the washing area or to allow it to accumulate, while the overflow valve is only used in the closed position of the valve body to allow the liquid to flow out of the washing area when the maximum level of the liquid in the washing area is exceeded is.
  • the head of the overflow valve is shaped like a segment of a sphere and a sealing surface in the valve body, against which the head of the overflow valve rests in a sealing manner in its closed position, is correspondingly shaped, annular. This ultimately creates a sealing surface and not just a sealing line between the valve body and the overflow valve.
  • the overflow valve is designed in the manner of a hollow cone and, in its open position, performs a tumbling movement due to the annular flow of the draining liquid.
  • the hollow cone-like design of the overflow valve contributes to providing the necessary buoyancy forces which keep the overflow valve in its closed position.
  • the tumbling movement of the overflow valve brought about by the annular flow of the liquid has the consequence that dirt can settle less easily on the overflow valve and on the valve device as a whole, which reduces the cleaning effort.
  • This further development therefore also contributes to the easier handling of the valve device according to the invention.
  • FIG Fig. 1 A schematic, perspective, exploded view of a valve device 1, in particular for a washing area, not shown in detail, in the sanitary area is shown in FIG Fig. 1 shown.
  • the valve device 1 can therefore in particular, but not exclusively, are used in a washing area, such as a washstand, a shower or a bathtub.
  • the valve device is usually located at the outlet of the washing area, that is to say in the position in which a liquid collected by the washing area, for example water, usually drains from the washing area.
  • the valve device 1 has a connection part 2, which is usually inserted from above into the drain, not shown, of the washstand, also not shown, releasably connected to a counterpart provided on the underside of the washstand and connected via the counterpart and a pipeline, not shown, to a not shown Siphon is connected.
  • the valve device 1 also has a valve body 3 which is designed to enable or block a flow through the connection part 2.
  • the connection part and valve body also function as a drainage part, with the aid of which liquid can drain out of the washing area or be accumulated in it.
  • the connecting part 2 has a stationary device 4 by means of which the valve body 3 can be held in its position for releasing the flow (release position).
  • the stationary device 4 is usually connected in one piece to the connection part 2. It is clear that the fixed device is therefore not movable in contrast to the lifting linkage described above in relation to the prior art.
  • the stationary device 4 is at least one projection 5, 6, 7 provided on the connection part 2, three projections 5 to 7, evenly spaced apart, being provided according to the illustrated embodiment.
  • the valve body 3 protrudes at least partially into the connection part 2.
  • the respective projection 5 to 7 is arranged on a tubular inner wall 10 of the connection part 2.
  • Each projection 5 to 7 protrudes a little into the free cross section of the connection part 2.
  • the valve body 3 sits in its in the Fig. 3 and 5 Approval position shown on the stationary device 4, preferably on the at least one projection 5 to 7.
  • the valve body usually rests on each projection 5 to 7 in its release position.
  • the projections 5 to 7 are arranged in the same horizontal plane.
  • the connecting part 2 and the valve body 3 are connected to one another so as to be movable relative to one another, the valve body 3 having at least one groove 12 on its outer circumference 11 for receiving the at least one projection 5 to 7.
  • a groove 12 is usually provided for each projection 5, 6 and 7.
  • the at least one groove 12 is located in that region of the valve body which protrudes into the connection part and is therefore arranged in all of its operating positions within the connection part.
  • the at least one groove 12 is designed and arranged in such a way that the valve body 3 can be moved from its position for blocking the flow (blocking position) to its release position and vice versa by means of a preferably counterclockwise rotary movement.
  • the release position of the valve body and thus the valve device is in the Fig. 3 and 5 shown.
  • the groove 12 has a first section 13 for raising / lowering the valve body 2 and a second section 14 adjoining the first section 13, with which the valve body 3 rests on the at least one projection 5 to 7 and thereby in its release position is held.
  • the raising / lowering of the valve body 3 takes place by means of a manually executable rotary movement of the valve body, the valve body being in its release position (see FIG Fig. 3 and 5 ) is in a raised position and in its locked position in a lowered position, in which the valve body protrudes deeper into the connection part compared to the release position.
  • the at least one projection 5 to 7 has a rounded top 15 and the second section 14 of the groove 12 has a corresponding bottom 16, so that the valve body 13 in the area of its rounded bottom 16 of the second section 14 of the groove 12 on the rounded top of each Can sit projection 5 to 7.
  • the sections 13 and 14 of the groove 12 are designed so that the valve body during its transfer is initially raised further and further from the locked to the release position and when the bottom 16 of the groove 12 in question slides completely onto the top 15 of the respective projection 5 to 7, it lowers again a little.
  • the valve body 3 has an overflow valve 17.
  • the valve body according to the invention can be used both in conventional washing places having an overflow device, such as an overflow opening and an overflow line connecting it to a drain pipe, and in washing places without such an overflow device.
  • the overflow valve 17 moves automatically out of its closed position which seals the valve body 3 when a maximum fill level of a liquid in the washing area is exceeded, as is the case in FIG Fig. 3 and 5 is shown in the direction of arrow A (see Fig. 5 ) into its open position allowing the liquid to drain off and vice versa.
  • the overflow valve 17 In its open position, the overflow valve 17 is moved away from the valve body 3 and to this extent spaced from it.
  • the overflow valve can be transferred from its closed to its open position and vice versa by the forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight.
  • the connection part 2 is connected to a connection element 20, as shown in dashed lines in FIG Fig. 5 is indicated.
  • the connection element 20 can be part of a siphon not shown in detail.
  • a liquid level 21 which is set up such that the overflow valve is usually in its closed position due to the forces acting on it, in particular the buoyancy forces, as is the case in FIG Fig. 3 and 5 is shown.
  • a liquid 22 into which the overflow valve 17 is at least partially immersed to such an extent that the buoyancy forces act on the overflow valve 17 in its closed position, provided that there is no liquid column above the overflow valve 17 which is such that it is the overflow valve transferred or pushes into its open position.
  • the overflow valve is located, as in Fig. 5 indicated, (also) in the release position of the valve body 3 in its closed position. In the blocking position of the valve body, the overflow valve is in its closed position until the maximum fill level of the liquid in the washing area transfers the overflow valve from its closed to its open position due to the hydrostatic pressure.
  • the valve body 3 has a circumferential sealing lip 23 which is moved away from the connection part 2 in the release position of the valve body 3, as is the case Fig. 3 and 5 demonstrate.
  • the projections 5 to 6 are in the area of the upper ends of the first section 13 of the grooves 12.
  • the valve body 3 has moved downward, ie towards the connection part 2, so far that the sealing lip 23 rests sealingly on an inner edge 24 of the connection part 2.
  • valve body 3 has a central opening 25 above its sealing lip 23, above which a cover 27 is held by means of ribs 26.
  • the cover 27 is thus spaced from the central opening 25.
  • cover 27 and ribs 26 are integrally connected to valve body 3.
  • the overflow valve 17 has a head 30 which is formed like a segment of a sphere. Furthermore, a sealing surface 31 in the valve body 3, on which the head 30 of the overflow valve 17 rests in a sealing manner in its closed position, is correspondingly shaped and configured in an annular manner. According to a preferred embodiment, the overflow valve 17, as in FIGS Fig. 1 , 3 and 5 indicated, designed as a hollow cone. The overflow valve 17, in its open position, in which the overflow valve with its head 30 has moved away from the sealing surface 31 of the valve body 3 in the direction of the arrow A due to the hydrostatic pressure of the liquid accumulated in the washing area.
  • circumferential ribs 32 which are located on the head 30 of the overflow valve 17 below the spherical segment-like surface of the head, as shown in FIG Fig. 1 is shown.
  • the ribs 32 extend along or parallel to the longitudinal axis 33 of the valve device 1 and thus also of the valve body 3. Set in the side view the circumferential ribs 32 continue the rounding of the spherical section-like part of the head 30 so that the overflow valve 17 can move within the valve body 3 in the manner of a ball joint.
  • valve device With the valve device according to the invention, soiling in the drainage area of a washing area is avoided. Dirt particles can neither hang nor get stuck on the device.
  • the valve device is also suitable for so-called attachment sinks, which can be stowed without an overflow opening.
  • the overflow and drainage functions are separated from one another.
  • the overflow valve 17 In the release position of the valve body 3, the overflow valve 17 is in its closed position due to the forces acting on it, in particular due to the buoyancy forces.
  • the overflow valve 17 serves exclusively to prevent the washing area from overflowing.
  • the head 30 of the overflow valve 17, which is shaped like a segment of a sphere, seals in all positions of the overflow valve as long as the overflow valve is in its closed position.
