Definitions

  • the invention relates to a two-way valve for a liquid-carrying household appliance, with a liquid inlet, two liquid outlets and a valve body which by the liquid can be moved into one of two closed positions in which it each closes a liquid outlet.
  • Two-way valves for selectively flowing two liquid lines can for example are used in washing machines or washer-dryers, For example, to rinse out the various detergent compartments of a induction bowl or to wash liquor or rinsing liquid at different operating phases in the Circulate circulation or discharge through a drain line.
  • a two-way valve can also be used in dishwashers to Conduct liquid flow to various spray arms or nozzles.
  • a two-way valve for a dishwasher is known from EP 0 237 994 A2, in which a valve body moves freely in a valve housing with two liquid outlets located and the liquid flow depending on the starting position of the valve body within the valve housing to one or the other other liquid outlet can be moved to close this. It is in this valve provided two starting positions, one of which is unstable and of the valve body is only ingested as long as the pump is switched off previously formed liquid column from one of the outlet lines of the valve as a result gravity flows back in the opposite direction through the valve. Otherwise the valve body assumes the other, stable starting position.
  • valve body can be switched off after the Pump only in the closed position of a certain time window Outlet are moved and then only in the closed position of the other outlet. It is therefore not possible to choose which output line at any time should be closed, and in particular one of the output lines outside of the time window at all without closing the pump again. This can lead to increased wear on the pump and / or loss of time to lead.
  • the invention has for its object a two-way valve of the aforementioned Way of creating by using simple, reliable and especially inexpensive Means the liquid flow can be controlled independently of the time, whereby the liquid outlets are also completely closable.
  • a two-way valve which is an actuating element has that steer the movement of the valve body in one of the closed positions can.
  • the control element does not have to be able to interrupt or direct the liquid flow and therefore not be sealed as the liquid outlet is sealed is achieved by the valve body. So it can be a very simple actuator be used, which is much cheaper and more reliable.
  • the valve body can be caused by the flow of liquid within the valve body and / or can be moved into the closed positions by its buoyancy in the liquid, whereby in the latter case the density of the valve body is less than that of the liquid.
  • the actuator can at least move the valve body mechanically block a locking position.
  • the control element can, for example be a simple magnetic plunger that moves into the range of motion when activated pushes the valve body and therefore controls its movement. He can do that specify possible trajectory or certain movement options block, so that the valve body only have to take a certain path can.
  • the actuator can also move the valve body in all closed positions block so that both fluid paths remain open.
  • valve body can also contain a magnetic substance and the actuating element Be set up so that there is a magnetic attraction on the valve body can exercise.
  • the adjusting element can be an electromagnet, for example be easily controlled by an electrical or electronic control device lets and advantageously from a closed valve housing non-magnetic material can act on the valve body, so that because of the control element no openings to be sealed arise.
  • the actuator can to be arranged at the point where the movement paths of the valve body branch to the two closed positions, and the direction of movement by an impulse change the valve body as soon as the liquid moves past it.
  • the two-way valve can be set up in such a way that the valve body is moved into a preferred closed position by the liquid, if the control element does not move the valve body into any of the closed positions directs.
  • This preferred closed position is preferably chosen so that the Liquid flow flows in the direction associated with less danger, so that at Failure of the control element or its control can cause less damage and fail-safe behavior of the valve is achieved.
  • This preferred direction of movement The valve body can pass through the liquid inside the valve body can be achieved by, for example, the liquid outlet with the preferred closed position is located in the extension of the inflow section of the valve, so that the valve body can be moved in a straight path by the liquid flow.
  • a preferred closed position can also be achieved by designing the Valve housing can be reached, in which the majority of the liquid through the liquid outlet exits with the preferred closed position so that the valve body there is moved if it is not influenced by the outside. Furthermore, movement in the preferred closed position is achieved or supported by the alignment of the valve be so that by gravity and the inflowing liquid respectively the rising liquid level in the valve housing is a preference results in a closed position. This is particularly possible with household appliances because in almost all cases these are set up vertically, so that by installing the Valve can also be guaranteed a certain orientation.
  • the actuating element can be designed so that it does not move the valve body only in the can steer preferred closed position, so that the adjusting element is designed more simply can be.
  • the control element In the preferred closed position, the control element must move the valve body in this case can not steer, because he can do this position without external interference can take through the actuator.
  • the actuating element can have a rest position when it is de-energized, in which it directs the movement of the valve body into the non-preferred closed position.
  • the actuating element can have a rest position when it is de-energized, in which it directs the movement of the valve body into the non-preferred closed position.
  • control element can be designed so that the movement of the valve body can alternately steer into the closed positions, so that The valve body is positively guided and in any case it is securely in the desired position Lock position is moved. This can be done by moving the valve body always be locked in at least one closed position so that it is free from the liquid is moved securely into the respective free locking position.
  • valve can be set up such that the adjusting element follows the valve body which can maintain a closed position within a range of which from the valve body of the liquid only in the previously taken closed position can be moved.
  • control element can move the valve body back lock in a position from which he can also reach the other closed position could.
  • a magnetic actuator without a tappet could leave the valve body after leaving hold it in a closed position and release it as soon as it is free of the liquid is set in motion safely.
  • a two-way valve according to the invention is in its installed position shown in a household washing machine in which a liquid 9 in the form of Soapy water or rinsing liquid either circulates through a laundry treatment room or pumped out through a drain line at the end of a treatment process shall be.
  • a liquid 9 in the form of Soapy water or rinsing liquid either circulates through a laundry treatment room or pumped out through a drain line at the end of a treatment process shall be.
  • this is the one downstream two-way valve according to the invention, with which the liquid 9 either in the circuit or to the drain pipe.
  • the valve has a housing 1 which has a liquid inlet 6 at the bottom and two at the top Has liquid outlets 7 and 8, towards which the housing 1 is located upwards The shape of a fork divides. Through the outlet 7, the liquid 9 is in the drain line pumped and circulated through outlet 8.
  • a spherical valve body 3 is freely movable within the housing 1 Density arranged, which is smaller than that of the liquid 9.
  • a tubular one Attachment 2 attached, which is fixed at one end in the housing 1 and liquid lines can be connected to its free ends.
  • the inside diameter the connecting pieces 2 is smaller than the diameter of the valve body 3, so that it cannot escape from the housing 1.
  • the form in the Housing 1 directed mouths of the fittings 2 valve seats for the valve body 3, so that it closes this at a connection piece 2.
  • the valve body 3 at least on its surface or are the connectors 2 at least at their contact areas with the valve body 3 made of elastic Material to achieve a better seal.
  • the valve body 3 can have three different end positions A, B and C at the three connecting pieces Take 2, with position A at the liquid inlet 6 and is taken when there is no liquid 9 in the housing 1 and the valve body 3 is pulled down due to its weight.
  • Position B is at the liquid outlet 7 and position C at the liquid outlet 8. The flow the liquid 9 in the area of the inlet or the outlets is through in both figures Arrows indicated.
  • the left side of the housing 1 is at the point where the housing 1 is facing the two liquid outlets 7 and 8 branches, an electromagnetic actuator 5 with a plunger 4 attached.
  • the plunger 4 projects obliquely in the rest position of the actuating element 5 up into the housing 1 so that it gives the valve body 3 access to the position C blocked.
  • the tappet 4 is withdrawn and gives access to position C.
  • Access to position B is through the plunger 4 in no position blocked.
  • the actuator 5 is shown in its rest position, in which the plunger 4 in the Housing 1 protrudes.
  • the valve body 3 is rising due to its buoyancy Liquid 9 raised from position A.
  • the valve body 3 on the tappet 4th hits, it is deflected to the right into the section of the housing 1 that leads to the liquid outlet 7 leads, and is pressed in position B to the connector 2 there, whereupon he blocks the liquid outlet 7.
  • the liquid 9 flows in this Condition only through the outlet 8 from the valve and is therefore in the circuit led through the laundry treatment room.
  • the actuator 5 is shown in the excited state in which the plunger 4 is withdrawn is and gives access to position C. If the valve body 3 in this Position of the plunger 4 is raised by the inflowing liquid 9 comes he in position C and closes the outlet 8 so that the liquid 9 through the Outlet 7 can be pumped to the drain line. This is due to the inclination of the Housing 1 and the vertically upward lifting force causes, so that the valve body 3 on its way up on the left at an angle above it Moved along the wall of the housing 1 and not in the right to the outlet 7th leading section of the housing arrives.
  • valve body 3 In order to move the valve body 3 from one closed position B or C to the other, it must be done by reducing the flow or level of the liquid 9 in the housing 1 in a position below the fork or the point of engagement of the tappet 4 and preferably brought back to position A. Thereupon the Adjustment element 5 of the plunger 4 brought into the other position.
  • the valve body 3 by increasing the flow or level of the liquid 9 in the housing 1 one of the other locking positions B and C moves. Influencing the flow or the level of the liquid 9 can be controlled by the pump or by a can be reached between the pump and the two-way valve shut-off valve, whereby itself with the intermediate valve usually a faster increase or Reduction in fluid flow is achieved.
  • valve body 3 A lifting of the valve body 3 by rapidly inflowing air before the actual one
  • liquid entry may also occur when the two-way valve is operated with the plunger 4 retracted, deflecting the valve body 3 in the direction of the position Cause B because the flow force of the air is directed to the top right and with the vertical downward force of gravity interacts.
  • the control of the pump can be set up so that an excessive air flow is prevented, or can be sufficient between the valve body 3 and the housing 1 Distance is provided to entrain the valve body by an air flow to prevent.
  • the valve body 3 can have a density greater than that of the liquid 9 provided that they are particularly difficult.
  • valve can also have more than two outlets, wherein the actuator either the valve body in one of the closed positions can guide, which are provided in the number of outlets, or being the actuator the movement of the valve body in at least one of these closed positions can block.
