Definitions

  • the invention relates to a drain fitting for whirlpool baths.
  • Whirlpools are characterized by the fact that they produce a water flow in a tub. Of course, since the tubs must also have an outlet to drain them, it makes sense to suck the water at this point and pump it back into the tub at another point. It is possible in this way to summarize both the suction of the water for pumping back and the sequence in a pop-up waste.
  • the invention is based on the object to improve a drain fitting for a whirlpool bath with regard to the safety of the operation.
  • the invention proposes a waste fitting with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • Theticiangamitur thus contains a suction chamber into which the water from the tub first passes, through an inlet opening in this suction.
  • the suction chamber contains a connection for the suction side of a pump. So this pump sucks in the water from the suction chamber and pumps it back to another place in the tub.
  • a passage leads to the waste run, this passage is closed by a valve.
  • This valve is similar to a normal drain valve from a bathtub. This drain valve is designed so that it normally remains closed, but it opens when the negative pressure is too large or when the absolute pressure in the suction chamber is too small.
  • this valve can also be opened by a manual device, as is also provided in drain valves conventional tubs.
  • the formation of the drain fitting in this way means that at too high a negative pressure in the suction chamber, the valve is opened, so that air can be sucked from the Abiauf. As a result, the negative pressure in the suction chamber is limited. If the excessive negative pressure is caused by a person in the tub closes the drain hole, thereby improving the safety of the people in the tub.
  • the inlet opening is arranged in the suction chamber at the top thereof, and that the outlet from the suction chamber is arranged at the bottom thereof.
  • the inlet opening into the suction chamber with a drain cup is connectable.
  • This drain cup is usually inserted from the inside of the tub in the drain opening of the tub and is on the edge of the drain opening usually with the interposition of a seal on.
  • other types of drainpipe can be used in existing plastic tubs.
  • the drain cup can be screwed into the inlet opening of the suction chamber and thereby defines the edge of the bottom of the tub between the drain and the drain set surrounding the drain opening from the tub. This serves at the same time also fixing the waste set to the tub.
  • a cover is provided which partially covers the drain opening from the tub and which is insertable into the drain opening of the tub.
  • the cover is formed together with a hair trap as an insert, which is in particular kelch insertion in the flow.
  • the insert is designed such that a lifting of the hair trap screen also raises the lid.
  • the cover should thus be arranged above the hair-collecting sieve or be otherwise connected to it in such a way that raising the hair-collecting sieve always leads to lifting of the cover.
  • Such hair trap screens are common in order to prevent hair or similar objects from entering the pump. Clogging of the hair sieve can also cause the negative pressure in the suction chamber to be too high.
  • the insert has a cylindrical end portion.
  • This cylindrical end portion corresponds in diameter to the cylindrical inner shape of the drain cup. If in the end portion has a certain length, it can be ensured in this way that the insert is guided over a greater distance, so that there is no risk of jamming. Tilting could obstruct the opening of the lid.
  • the drain valve has a valve seat and a valve closing body, in Closed position is applied.
  • This admission in the closed position can be done for example by a spring. But it is particularly favorable when the valve closing body is subjected to weight. There is then no additional element required. By the size of the weight can be adjusted at which value of the negative pressure, an opening of the valve takes place.
  • valve closing body is zugverbunden with the lid. This means that you can also lift the Venüischitigenia when lifting the lid.
  • connection between the cover and the valve closing body is formed such that a lifting of the lid opens the drain valve, but the opening of the drain valve does not lift off the lid.
  • the drain valve should always work when the value of the negative pressure exceeds a certain value.
  • the valve should always open to drain. For example, if a person gets their hair into the hair trap and pulls, should be opened by pulling on the hair trap or the lid immediately and the drain valve so immediately the negative pressure is reduced by sucking air from the drain.
  • One way to connect is a telescopic connection.
  • This can, for example, be such that a tube with at least one longitudinal slot closed to the free end of the tube is arranged on the underside of the lid, into which a rod arranged on the upper side of the valve closing body engages in a sliding manner.
  • a tube with at least one longitudinal slot closed to the free end of the tube is arranged on the underside of the lid, into which a rod arranged on the upper side of the valve closing body engages in a sliding manner.
  • the reverse arrangement is suitable.
  • valve closing body may also have on its underside a rod which is guided in a socket. This also serves to guide the valve closing body so that tilting or tilting can not occur.
  • the drain chamber has a connection for a tub overflow. This serves to allow air to be sucked out of the tub overflow when the securing device formed by the opening of the valve responds.
  • the insert of hair trap and lid is integrally formed.
  • the entire waste set may have a unitary housing or a two-part housing in which the moving parts are arranged. These parts can be made of plastic
  • FIG. 1 shows part of the floor 1 of a whirlpool bath.
  • an outlet opening 2 is arranged, whose edges are bent downwards.
  • the drain fitting is arranged below the drain opening 2, the drain fitting is arranged.
  • the drain fitting includes a housing which contains in its upper region an opening which is provided with an internal thread 3.
  • an internal thread 3 of the opening of a drain cup 4 is screwed from the inside of the whirlpool tub 1 ago.
  • a seal 5 is inserted. This is determined by screwing the Ablaui'keichs 4 in the internal thread 3 of the pop-up waste.
  • the drain cup 4 includes a cylindrical sleeve extension 6 below its upper flange 5. This extends into the drain fitting. This sleeve portion 6 forms on its inside a cylindrical contact surface.
  • the drain fitting includes two housing sections 7, 8, which are screwed together by means of a hub 9.
  • a connection 10 for a line is formed on the left side in Figure 1, which leads to the suction side of a pump.
  • a connection 11 is formed for a further line, which can be used for further purposes.
  • Between the two terminals 10, 11 leads a drain valve in the underlying housing section 8, from which in turn leads to the bottom of the drain out.
  • the drain valve contains a valve closing body 13 and a valve seat 14 cooperating therewith.
  • the valve closing body 13 has on its underside a rod 15 which is guided in the already mentioned hub 9 in the axial direction.
  • the valve closing body 13 On its upper side, the valve closing body 13 also contains a rod 16 which extends in the axial extension of the rod 15 arranged on its underside.
  • the rod 15 In the illustrated closed position of the drain valve, in which the valve closing body 13 rests with its seal on the valve seat 14 and thus closes the valve, the rod 15 protrudes on the underside of the hub 9 out of this and forms one in the drain section 8th lying attack point to manually open the drain valve by means of an indicated lever 17.
  • This lever 17 is actuated via an actuating device, not shown, which engages from the right into the housing portion 8.
  • an insert 18 is inserted, which has a cylindrical portion 19.
  • This cylindrical sleeve portion 19 corresponds in its outer diameter to the inner diameter of the cylindrical extension 16 of the drain cup 4. It is thus guided on the abovementioned contact surface on the inside of this section 6.
  • the insert 18 can be inserted from above and removed upwards.
  • the insert contains a lid 20, which is solid and whose outer diameter corresponds approximately to the outer diameter of the flange portion 5 of the drain 4. Below the lid 20, a hair trap 21 is formed in the insert 8, which has a plurality of perpendicular to the top of the lid 20 extending slots. The slots open into the cylindrical outer side 22 of the insert 18.
  • a tube 23 is integrally formed, which contains in its wall two longitudinally extending slots 24. In a cross section through the tube 23, the slots are arranged diametrically. They do not reach all the way to the end of the tube 23.
  • the upper end of the rod 16 of the valve closing body 13 is inserted into the tube 23.
  • the outer end of this upper rod 16 includes a transverse bore into which a pin 25 is inserted, which projects beyond the rod 16 on both sides and thereby limiting the movement of the rod 16 in forms the tube 23.
  • the valve-closing body 13 is characterized limited relative to the lid or the insert 18 in the axial direction movable, on the other hand, the cover 20 and the insert 18 with the valve closing body 13 is zugverbunden.
  • This tension connection between the insert 18 and the valve closing body 13 is designed such that the valve closing body 13 can be lifted off the valve seat 14 in order to open the drain valve formed by these two parts without the insert 18 being moved as a result.
  • This condition is shown in FIG. Here, the valve closing body 13 is lifted from the valve seat 14, while the insert 18 is unchanged.
  • the transverse pin 25 In the closed position of the drain valve, see Figure 1, the transverse pin 25 is just above the lower end of the two slots 24. In the open position of the drain valve, see Figure 2, the transverse pin 25 is approximately in the middle of the longitudinal extent of the two slots 24th
  • the outer diameter of the valve closing body 13 is slightly smaller than the inner diameter of the cylindrical projection 6 of the drain cup 4. For cleaning, it is possible to pull the insert 18 upwards, which causes the valve closing body 13 of the drain valve is entrained and through the professionkelch 4 can be pulled upwards.
  • the valve closing body 13 is due to its weight, which is determined by the rods 15 and 16 and its own thickness, on the valve seat 14, so that the drain valve is closed.
  • the pump sucks water through the connection 10, which flows down through the hair trap 21.
  • the drain valve and the drain opening 2 is created by a reduced pressure.
  • This housing section thus forms a suction chamber. The value of this negative pressure in the suction chamber is determined by the cross section of the openings and the power of the pump.
  • the device In normal operation, the device is tuned so that this normal negative pressure is not sufficient to lift the acted upon by its weight valve closing body 13 of the valve seat 14. If, for some reason, there is too great a negative pressure in this suction chamber, this will cause the valve-closing body 13 to be lifted off the valve seat 14, thus opening the drain valve. Now air can be sucked both from the tub overflow from the line 26 and from the drain 12 to release the negative pressure. Too much negative pressure would cause too much water to be sucked out of the tub, which could endanger persons in the whirlpool tub.
