Definitions

  • the invention relates to a metering valve for metering liquid funds for household appliances according to the generic term of claim 1.
  • the intermediate chamber in these devices is over one Sealed membrane attached to the sealing element of the Valve body is molded.
  • the invention has the task of a metering valve to propose with increased operational safety.
  • This task is initiated by a valve mentioned type in that the drain from the over Diaphragm sealed valve chamber branches.
  • this valve chamber can be in the de-energized state always empty completely, so that with the exception of the short ones Filling intervals of the valve chamber during the operation of the Household appliances this chamber is empty.
  • an intermediate chamber between the inflow a storage container and the membrane seal sealed valve chamber is provided.
  • the intermediate chamber is used to dose the agent opened until it is filled. Then it is from Inflow separated and connected to the valve chamber from the the drain branches off. This will change the content of the Intermediate chamber supplied the appropriate use. By Repeating this mode of operation can also be repeated dose a multiple of the inter-chamber volume.
  • the Connection between the intermediate chamber and through the Diaphragm sealed valve chamber through a first Closing element of the closing body made.
  • the Interruption of the supply of funds according to the invention for Valve chamber with the drain in the de-energized state is thus through the closing mechanism between the intermediate chamber and the valve chamber. This leaves the intermediate chamber always filled in the de-energized state, so that immediately with Actuation of the closing body the desired one Corresponding amount of detergent over the intermediate chamber Valve chamber and its drain can drain.
  • a second Closing element for separating the inflow from the Intermediate chamber provided, which is preferably in push-pull to first closing element is actuated. This means that the Inflow to the intermediate chamber is open when access to the Valve chamber and thus blocked for drainage. Subsequently the inflow to the intermediate chamber is closed during the Passage from the intermediate chamber to the membrane-sealed Valve chamber and thus opened to drain.
  • both the first closing element and the second Closing element mechanically, e.g. B. on a common Valve tappet, coupled.
  • This can be done, for example be accomplished that the closing elements immediately on Valve tappets include sealing surfaces attached to Actuation pressed on or off corresponding valve seats be spaced.
  • additional ventilation is provided on the intermediate chamber. This venting is used to open the connection between the intermediate chamber and the membrane-sealed valve chamber the agent to be dosed lighter and therefore faster can drain off. The dosage can therefore be faster overall and especially only with the help of the gravity of the agent without an additional pressure pump.
  • a sealing element which integrally both both mentioned closing elements as well as the membrane seal includes.
  • This sealing element thus fulfills the functions described above, with the sealing of the Valve chamber by means of the membrane at the same time the separation of the Valve tappet from the agent to be dosed in Touching areas of the metering valve becomes.
  • the formation of this sealing element in one piece Form further reduces the manufacturing of the metering valve required parts with a corresponding reduction in Manufacturing costs. Because no different sealing elements joined together or with other components there is also greater scope in the Manufacturing tolerance possible. This will Manufacturing effort also reduced.
  • the Closing body or the valve lifter as from the anchor of electromagnetic coil running separate part. over an appropriate mechanical coupling can be attached Function of the metering valve can be ensured.
  • Function of the metering valve can be ensured.
  • the actuation of the closing body can have many different types of actuators take place, for example via rotary levers or the like, where appropriate by using appropriate Power ratios also have a smaller dimensioning electromagnetic coil is possible.
  • a reset element for. Legs Spring or the like provided by means of which Closing body in the desired position at not loaded coil is held.
  • the metering valve 1 comprises an inlet 2 and an outlet 3 for a detergent.
  • the drain 3 branches from one Valve chamber 4 from the outside through a membrane 5th is sealed.
  • the membrane 5 is on a sealing element 6 molded on, which is attached to a valve lifter 7.
  • the Valve tappet 7 has an elongated shape and includes one conical section 8 to which the sealing element 6 hugs. Accordingly, the sealing element 6 on the Outside also a conical sealing surface 9 formed as the first closing element between the Valve chamber 4 and an intermediate chamber 10 is used.
  • the valve lifter 7 is also provided with an annular projection 14 provided on which the correspondingly formed sealing element 6th locked.
  • the membrane 5 opens into an annular bead 15, which in a Recess 16 between an annular shoulder 17 of the Valve housing 18 and a cover 19 is inserted. Of the Ring bead 15 is sealing both on the valve housing 18 and also on the lid 19.
  • Ventilation line 20 for venting and venting the Intermediate chamber 10 is provided.
  • the valve lifter 7 has a termination 21 with an enlarged Cross-section so that there is an undercut 22, an actuator can attack.
  • the conclusion 21 in conjunction with the undercut 22 thus forms Coupling element 23.
  • the dosage of the detergent flowing in via the inflow 2 is done by successive impulses Actuation of the valve lifter 7. Shown in the de-energized state State of the metering valve 1 is the sealing plate 13 down pushed so that the connection between the inflow 2 and the intermediate chamber 10 is opened via the passage 12. Thus, detergent can flow into the intermediate chamber 10 wherein air can escape through the vent line 20.
  • Valve tappets 7 are tightened in the direction of arrow P.
  • the passage 12 of the Inflow 2 to the intermediate chamber 10 closed.
  • the sealing surface 9 of the passage 11 between the intermediate chamber 10 and valve chamber 4 lifted off. So detergent from the Intermediate chamber to reach the drain 3 via the valve chamber 4. This drainage is caused by the ventilation via line 20 facilitated.
  • Valve tappet 7 By ending the current application the Valve tappet 7 by not shown Reset elements returned to their starting position, so that the passage 11 between the intermediate chamber 10 and Valve chamber 4 is closed. It can therefore not Detergent in the valve chamber 4 via the inflow 2 and the Flow through intermediate chamber 10. Any detergent residue from the already emptied valve chamber 4 can freely over the Drain 3.
  • the elastic membrane 5 is thus in the currentless state and therefore not in contact with most of the time Detergent.
  • the tightness requirements of the Membrane seal 5 are reduced.
  • a valve of described type therefore has great operational reliability on.
  • the volume of the intermediate chamber 10 represents the maximum volume of rinsing liquid which, when the valve tappet is tightened 7 can drain off. Even if the valve is defective Position remains the membrane 5 without contact to Detergent, since in this case the passage 12 between the Inflow 2 and the sealing chamber 10 is closed.
  • the sealing element 6 comprises the two closing elements 9, 13 to separate the intermediate chamber 10 from the inflow 2 and from the valve chamber 4 and is at the same time with the membrane seal 5 provided to seal the valve chamber 4 to the outside.
  • the sealing element 6 further isolates the valve lifter 7 from Inside of the metering valve 1.
  • a metering valve 1 of this type consists of a total comparatively few individual parts. In particular, there is only one only sealing element 6 to ensure all necessary Closing and sealing functions necessary. This will Manufacturing effort significantly reduced.
