Definitions

  • the invention relates to an adjusting device for a control of a water diverter for a water-conducting domestic appliance according to the preamble of claim 1, a method for adjusting an adjusting device according to the preamble of claim 13 and a use of a synchronous motor according to claim 16.
  • water switches are arranged in the rinse water circuit, which are provided with differently designed flow openings.
  • the water diverter is adjusted by a certain angle of rotation, so that another flow opening flows through the rinse water and thus a different amount of water is provided.
  • the water switch is rotatably mounted on a shaft which is driven by an electric motor.
  • On the shaft also synchronized with the water switch control disk is attached, via which the current angle of rotation of the water switch is determined.
  • the electric motors used are motors that can only rotate in one direction or were controlled in such a way that only one direction of rotation is possible.
  • a disadvantage of such an arrangement is that the predetermined by the various angular positions of the control disk flow states of the water switch can be controlled only sequentially. For example, the repetition of the last pass state is only possible by the sequential passing over of all other pass states stored on the control disk possible.
  • the flushing process must be interrupted. This lengthens the duration of the washing program.
  • the present invention is therefore based on the problem of providing an adjustment of a water diverter for a water-leading household appliance and a method for adjusting a water diverter and the use of a synchronous motor, by means of which the rinsing time of rinsing programs can be shortened, or reduces costs can be.
  • the first object with respect to an adjusting device is achieved by a control of a water distributor of a water-conducting household appliance, wherein the adjusting device controllable by an electronic control motor, a water separator with a control for influencing the detergent circuit, means for transmitting the rotation of the electric motor to the control and means for determining the position of the control, wherein the electric motor is a left and right-handed, single-phase synchronous motor with two terminals.
  • the adjusting device further comprises means by means of which the position or rotational position of the control element can be determined.
  • the electric motor is a left- and right-handed single-phase synchronous motor with two connections.
  • a slower rotating electric motor can be used to shorten the Spülprogrammdauer.
  • Such an engine can be made in a smaller construction and therefore manufactured more cheaply.
  • the motor's torque is lower in terms of torque. Ie. when the engine is rotated slowly, a higher torque is available despite the smaller design of the engine to adjust the control.
  • the second object with respect to a method for adjusting is achieved by an adjusting device according to one of the preceding claims for a control of a water diverter for a water-bearing household appliance, wherein the adjustment angle of the control is determined by a means for determining the position of the control, and wherein the control is adjusted by a left- and right-handed synchronous motor whose direction of rotation is determined by the control electronics and the control is half-wave direction.
  • the control of a water distributor is adjusted by the position of the control, so its adjustment is determined by a means and the adjustment before adjusting the control by means of a left and right-handed, half-wave controlled synchronous motor whose direction of rotation is set by the control electronics to the desired adjustment angle of the control is rotated, so that the required flow rate of detergent can flow through the control.
  • the third object with regard to a device is achieved by using a left and right-handed, single-phase, two-port synchronous motor for adjusting an adjusting device according to one of the preceding claims for a control of a water separator for a water-conducting household appliance.
  • a Hilfswindlungskaya synchronous motor has the advantage of being inexpensive to produce and on the other to be controlled in a simple manner.
  • control electronics determines the direction of rotation of the synchronous motor, and the control is effected half-wave.
  • the means for transmitting the rotation of the synchronous motor to the control element comprises a shaft.
  • the means for determining the position of the control element via a signal line to the control of the synchronous motor is connected.
  • the control signals can advantageously be a wired signal line or a wireless signal line, ie by means of transmission by electromagnetic waves are used.
  • the means for determining the position of the control element is a synchronizing switch and a control disk, which is non-rotatably connected to the control element.
  • the control disk can be a cam disk by means of which the synchronizing switch is actuated.
  • the control disk for example, as the control rotatably mounted on a shaft and thus be rotated by an identical adjustment angle as the control.
  • the means for determining the position of the control element is a sensor for a parameter of the domestic appliance.
  • a determination of the position of the control by a sensor, the electronic readability of the sensor signal by the control electronics and thus a cost-effective analysis of the state is possible.
  • sensors can be understood both physical sensors as well as the determination of current or voltage.
  • the parameter of the domestic appliance is the flow rate of water in the detergent circuit and / or the pressure in the detergent circuit and / or the current consumption of the pump driving the detergent circuit.
  • the measurement of the current consumption is particularly favorable since no additional sensors are required for this purpose and the tap for determining the current consumption can be arranged on the printed circuit board of the controller.
  • control of the water distributor is enclosed by a housing which has an inlet and a drain for the detergent circuit.
  • a housing which has an inlet and a drain for the detergent circuit.
  • control has a number of differently dimensioned openings for setting different flow states.
  • control element is designed as a disk or as a tube with radially arranged openings.
  • the adjustment angle of the control element is determined via a control disk which interacts with a synchronizing switch and which is synchronized with the control element.
  • the adjustment angle of the control element is expediently determined via a sensor for determining the flow rate of water in the flushing agent circuit and / or the pressure in the flushing medium circuit and / or the current consumption of the pump driving the flushing agent circuit.
  • FIG. 1 shows in the form of a schematic representation of an adjusting device 10 for a control 16 of a water switch of a water-conducting household appliance.
  • the adjusting device 10 has a synchronous motor 14, which is connected via a shaft 20 with a control unit 16, which is arranged in a housing, not shown. About this shaft 20, the direction of rotation of the electric motor 14 is transmitted to the control element 16 and the displacement angle 34 of the control 16 is deflected.
  • a gear 22 is arranged on the shaft 20 of the adjusting device 10 which can be configured as a subordinate or translating gear.
  • control element 16 has a number of differently dimensioned openings 34.
  • the water supply and water drain in the housing, not shown, is indicated by arrows. It is envisaged to combine a water inlet with a water outlet or, in a preferred alternative, to combine a water inlet with at least two water drains, wherein the at least two drains can be fed through different openings 34.
  • electric motor 14 is a left and right-handed single-phase synchronous motor with two terminals is executed without Hilfswicklungskay and whose control is half-wave direction. About an electronic control unit 12 of the synchronous motor 14 is driven, set the direction of rotation and the control 16 is adjusted.
  • means 24, 26, 28 are provided for determining the position of the control element.

  • the control electronics 12 is connected via a signal line 30 to the synchronizing switch. This can be a wired as well as a wireless signal line.
  • a sensor 28 can be used to determine a parameter of the household appliance.
  • the sensor 28 may be a flow meter in the flushing agent circuit, a pressure gauge in the flushing agent circuit and a measuring device for determining the power consumption of the pump driving the flushing agent circuit 18. Depending on the need for precision, these sensors can be used individually or in various combinations with each other be used.
  • the sensor signal of the sensor 28 can be transmitted via a signal line 32 to the control electronics 12. This can be a wired as well as a wireless signal line.
  • the reversible control of the synchronous motor 14 for example, the direction of rotation from right to left rotation reversible and thus the control element 16 in the forward and reverse rotational direction movable and thus the adjustment angle 36 adjustable. Due to this particularly advantageous embodiment, it is possible to achieve a time savings when passing through the washing program, since the waiting time during adjustment of the control element 16 as a result of the reversible direction of rotation is significantly shortened.
  • an electric motor 14 of substantially smaller design can be used. The smaller design requires less material and thus allows significantly reduced component costs.
  • the adjustment angle 36 of the control element 16 is determined by a means 24, 26, 28 for determining the position of the control element 16. This may be a sensor 28 for determining the machine parameters or a control disk 24 in combination with a synchronizing switch 26.
