Definitions

  • the invention relates to an electrical control device a washer or dryer with one Control electronics, the speed of a Drum motor controls via at least one triac and recognizes a triax short circuit, and with one electromechanical program switching mechanism, the one Program drum, a reversing drum and a Has drive unit, the reversing drum Reversing contacts for clockwise rotation, standstill, counterclockwise rotation of the Drum motor cyclically controls, and the Control electronics in the event of a short circuit The reversing contacts switch to "standstill".
  • Such a hybrid control device is in the EP 0 695 982 A1.
  • the control electronics receives from the program drum program control commands and stops the reversing drum for the desired duration of the Cycle functions: clockwise rotation, standstill, counterclockwise rotation, Standstill by turning on the power pack that the Program drum and drives the reversing drum, stops.
  • the program drum switches one at a time Program step further if the cycle functions have gone through several times.
  • a short circuit of the triac the control electronics recognizes, for example, that due to the short circuit of the laundry drum motor to one undesirably high speed runs up.
  • the control electronics then let the drive unit continue to run that the reversing contacts go into the standstill position.
  • the laundry drum motor can thus despite the short circuit of the Triacs stop running.
  • After one Safety shutdown at which the program control sequence the others remain Units of the washing machine or dryer continue on the supply network. This leads in particular problems with the heating, since the wash liquor is now evaporated due to continuous heating and the evaporated
  • the object of the invention is an electrical Control device of the type mentioned to propose with in the event of a triac short in a simple way at least the heating device is switched off.
  • the above object is characterized by the features of characterizing part of claim 1 solved.
  • a control device of a washing machine has electromechanical program switching mechanism 1 and one Control electronics 2 on.
  • the program switching mechanism 1 comprises a program drum 3 and a reversing drum 4, the from a common drive unit 5 gradually are drivable.
  • the drive unit 5 includes one Stepper drive, for example ratchet drive, and a timer motor driving this.
  • the Drive unit 5 is operated by an electronic switch 6 of the control electronics 2 switched on and off.
  • the Program drum 3 are 7 via coding contacts respective position of the program drum 3 corresponding Control commands to the control electronics 2.
  • a laundry drum motor 8 is 9.10 in via reversing contacts Reversing cycles Z in clockwise rotation, standstill, counterclockwise rotation, Standstill controllable.
  • the reversing contacts 9.10 are from the reversing drum 4, especially one or two accordingly designed cam discs of the Reversing drum 4, controlled.
  • a reversing section RA the reversing drum 4 comprises a plurality of reversing cycles Z (see Fig. 2).
  • the reversing section RA corresponds to one Program step of the program drum 3.
  • a heater 13 for heating the wash liquor is used by a contact 14 of the program drum 3 switched.
  • Other units 15 of the washing machine, such as Valves, pump, are also from contacts of the Program drum 3 switched.
  • laundry drum is a door of the Washer or dryer in the usual way assigned, loading through the door and the laundry drum is unloadable.
  • the door works with one Door locking device 16 together, the one Has switch S2, the mechanically with the door is coupled and can only close when the door closed is.
  • Switch S2 is in series with the network LN and the laundry drum motor 8 and the heating device 13 and the other units 15 of the washing machine. As long as the door is open, no unit 15 can therefore switch on the washing machine. The door can only be opened when switch S2 is open.
  • the door locking device 16 contains a for example thermal, delay element 17, the formed by a bimetal or a PTC resistor can be.
  • the delay element 17 determines one Hold time for holding switch S2 in its Closed position. Switch S2 only opens when it expires the hold time.
  • Control contact S1 provided, in series on the LN network to the delay element 17.
  • the control contact S1 is from another cam disk of the reversing drum 4 controlled (see Fig. 1). Is the control contact S1 is closed, then the delay element 17 flowed through so that the Door locking device 16 is active, that is Switch S2 is kept in the closed state, and thus the Door cannot be opened. Is the control contact S1 open and the hold time of the delay element 17 elapsed, then switch S2 goes into its open position so that the units 15 of the Washer are turned off and the door is open can be.
  • the control contact S1 is from the reversing drum 4 closed when the reversing contacts 9.10 on clockwise rotation or counterclockwise rotation of the laundry drum motor 8 are switched. If the reversing contacts 9, 10 are at "standstill", then the control contact S1 opened.
  • the Reversing cycle Z is in four successive angular or Time ranges a, b, c and d divided.
  • area a are the reversing contacts 9.10 on “clockwise rotation” and the Control contact S1 is closed.
  • area b and d the reversing contacts 9, 10 are at "standstill” and the control contact S1 is open.
  • area c are the Reversing contacts 9.10 on "counterclockwise rotation” and the Control contact S1 is closed.
  • the control electronics 2 detects this, for example, because the speed of the laundry drum motor 8 exceeds a limit due to the short circuit or the motor current exceeds a limit.
  • the Control electronics 2 then switches the reversing drum 4 so on that the reversing contacts 9.10 in the Go to standstill position and stop the further Program progression. This makes the laundry drum motor 8 separated from the LN network.
  • the Control contact S1 opened so that after the Delay element 17 also determined the holding time Switch S2 opens. By opening switch S2 the other units 15 of the washing machine and in particular, the heater 13 is switched off and even if the program drum 3 controlled contact 14 is still closed.
  • the heater 13 or the other Aggregates 15 with a triac short still can continue to work according to the program. This is convenient because such continued work on an entered Triac short circuit to significant interference or additional damage to the washing machine and / or the Can lead to laundry.
  • the heater 13 and optionally the additional units 15 is also advantageous in that In the event of a triac short, the program drum 3 must be brought into a position in which it Heating device 13 and the other units 15 switches off. Such a measure would be with one considerable switch-off delay and with higher Control effort connected.
