Definitions

  • Household appliance in particular household dishwasher
  • the invention relates to a household appliance, in particular a domestic dishwasher, at least comprising a treatment room, which can be opened and closed with a door of the household appliance for loading and / or unloading, further comprising at least an operation display with at least one optical and / or acoustic display means at least for indicating and / or signaling a completed treatment process of a product to be treated in the treatment room,
  • Household appliances have an operation display with at least optical display means, for example LEDs, with which during operation of the household appliance operating parameters, etc., and after completion of a
  • Treatment process can be displayed according to a program that the treatment process has been completed. However, the household appliance remains at the end of the program on the power grid until the customer actively intervenes and turns off the household appliance by pressing the main switch.
  • the object of the invention is to provide a domestic appliance, in particular household dishwasher, in which the energy consumption is further reduced.
  • Device door position detecting means are provided according to the invention, wherein detection of at least one selected appliance door position by the
  • Device door position detecting means towards at least the display means is deactivated.
  • the invention is based on the finding that conclusions can be drawn on the basis of a current door position of the appliance door after completion of the treatment process or after the end of the program as to whether the operation of the optical display means is still required for the user or not.
  • the program end display means can be deactivated.
  • the program end display means can be deactivated.
  • the inference can be drawn that the user is already informed about the end of the program and by opening the door in an ajar position or a half-open position first
  • Device door position detecting means for deactivating the display means is in signal communication with a control device of the household appliance, and that the
  • Control device on a selected door position representing signal of the device position detecting means towards the display means deactivated offers the advantage that the device door detection means can also be used as triggering means for other functions which are triggered by the control device of the home appliance, such as e.g. the switching on of an interior lighting of the treatment room.
  • Device door position detecting means for interrupting a power supply supplying the display means is formed when the selected
  • the appliance door position detecting means stops detecting the selected door position to deactivate the display means
  • Display means with electrical energy supplying power supply By a particularly simple construction is achieved in which the appliance door detection means act as a switch which interrupt a power line which supplies the display means with electrical energy.
  • the selected appliance door position in which the program end display means are disabled may be between a fully open and a fully closed appliance door position. When the door position of the door is fully open, the end-of-program display means may also be reactivated.
  • the above-mentioned selected appliance door position for example in the case of a domestic dishwasher, may be an ajar position or a half-open position in which loading and / or unloading of the treatment space is prevented, which usually can only take place in the fully open appliance door position in which the appliance door is in the horizontal plane in the case of a domestic dishwasher.
  • optical display means can also be deactivated at least partially automatically after a completed treatment process, if appropriate immediately after the detection of the above-mentioned selected appliance door position.
  • the appliance door position detecting means may comprise at least one Hall sensor.
  • the use of Hall sensors in door locking systems is well known.
  • the Hall sensor acts with a
  • the Hall sensor may therefore for example preferably be fixedly arranged on a housing of the household appliance and cooperate with a magnet arranged in the usually pivotable door.
  • the Hall sensor can also be arranged on the appliance door.
  • a Hall sensor arranged in this way detects whether the appliance door is closed or opened. Therefore, if an open position of the appliance door is detected by the Hall sensor, a controller of the household appliance which is in signal communication with it can generate the switch-off signal, to which the display means can be deactivated.
  • at least one inclination switch can be used as the device door position detection means, which can be a pivoting adjustment from an exemplary vertically closed door position to an oblique position of the appliance door detected.
  • an angle measuring device can also be used instead of the inclination switch.
  • the power switch and a circuit breaker are arranged in parallel.
  • the power grid may e.g. abut on a microswitch formed switch and the switching element connected in parallel thereto.
  • both the power switch and the switching element are open.
  • the deactivated, that is open switching element of the self-holding contact circuit can be bypassed, whereby the control device is acted upon by a voltage pulse.
  • the voltage pulse is passed via the control device to the self-holding contact circuit, whereby the self-holding contact circuit closes the switching element. In this way, current flows from the network via the now closed switching element
  • the power switch and the off switch an input and / or off-pulse are transmitted to the control device. It is further preferably provided that the power supply with the power switch and the circuit breaker is arranged forming a series circuit. In addition, it is preferably provided that the control device is connected to the power supply with electrical energy supplied. It is further preferably provided that the operating display is connected to the power supply with electrical energy supplied. Finally, it is preferably provided that the self-holding contact circuit is assigned to a controllable by the controller control.
  • the self-holding contact circuit may preferably have a bistable relay with which a relay contact acting as a switching element can be switched.
  • a bistable relay is characterized above all by the property that it can assume two different stable switching states when de-energized.
  • a relay contact of the bistable relay may be connected as the switching element in the main supply line of the household appliance. If the bistable relay is energized with the turn-off signal, it switches the relay contact from a stable de-energized open state to a stable de-energized closed state, or vice versa, whereby the household appliance is completely de-coupled from or connected to the mains.
  • a flip-flop in particular an RS flip-flop, can also be used.
  • the self-holding contact circuit is connected to the circuit breaker such that the circuit breaker can be brought into an open state, so that a separation of the supply voltage is possible in a simple way.
  • Household appliance evaluated.
  • the detected appliance door position is compared in the evaluation unit. If the detected appliance door position corresponds to the selected appliance door position, then the control device can deactivate at least the visual display means.
  • FIG. 1 is a schematic perspective view of a household dishwasher.
  • FIG. 2 shows a circuit arrangement of the household dishwasher;
  • FIG. 3 in a schematic representation of the household dishwasher with
  • FIG. 1 is shown as an exemplary embodiment of a household appliance, a household dishwasher with a front door GT, which is pivotable in a known manner about a bottom horizontal pivot axis and opened with a feed opening of the washing compartment BR for loading and / or unloading can be closed.
  • the feed opening is bounded above by a control panel B, which carries a micro-switch ES and only indicated optical display means AZ a power indicator BA.
  • input means E are provided with which operating parameters for a rinse cycle of the domestic dishwasher can be entered.
  • Fig. 1 in the left area of the control panel B microswitch ES is exemplified here as a key switch.
  • the domestic dishwasher can be switched to operational readiness, while in a subsequent printing operation, the household dishwasher is decoupled from the power grid.
  • Micro switch ES and the operating indicator BA are integrated. In the shown
  • Circuitry is the household dishwasher over a
  • Main supply line H connected to the power supply network.
  • Main supply line H is a later-described switching element AS and a power supply NT connected in series.
  • the power supply unit NT converts the mains voltage of, for example, 230 V into a low voltage of 12 V.
  • the low voltage 12V is converted into a low voltage of 5 V by means of a regulator RG connected in series with the power supply NT, with which a control device SE is supplied.
  • the power supply unit NT also supplies additional device components via additional outputs as well as the low-voltage household appliance operating indicator BA.
  • the control device SE is integrated in a control module not shown in detail and controls during the execution of a wash program via a first signal line SL1 the optical display means AZ of the operation indicator BA and other device component, such as the drain pump or the circulation pump, by means of control signals S E.
  • control device SE with a
  • the appliance door GT At an inclination angle ⁇ of 90 °, the appliance door GT is in its fully open approximately horizontal position, in which loading and unloading of the washing compartment BR is possible. Such loading and unloading of the domestic dishwasher, by contrast, is largely prevented at an angle of inclination ⁇ of the appliance door GT between the completely open and completely closed appliance door GT.
  • the control device SE In order to evaluate the current inclination angle ⁇ , the control device SE according to FIG. 2 has an evaluation unit AE, in which the detected inclination angle ⁇ is compared with the predetermined angular positions 0 and 90 ° of the appliance door GT. Depending on the result of this comparison, the evaluation unit AE of
  • Control means generate a switch-off SE from S through which the AS switch is controllable into its open position, as described later.
  • control device SE is connected via a second signal line SL2 to a bistable relay RE of a self-holding contact circuit SKS.
  • bistable relay RE is the relay contact already mentioned
  • Associated switching element AS which is connected in place of a mechanical main switch in the main supply line H and as such assumes a main switch function with which the household dishwasher can be decoupled from the power supply network or connected to it.
  • the household dishwasher is thus switched ready for operation, so that subsequently by means of the input means E, a washing program can be started. After the end of the washing program, the control device SE switches the
  • Device components such as lye or circulation pump off.
  • Control device SE a comparison of the currently detected inclination angle ⁇ with the preset angular positions 0 and 90 °. If an inclination angle ⁇ of 0 is detected, the evaluation unit AE recognizes that the appliance door GT is closed. If the detected inclination angle ⁇ lies between 0 and 90 °, or if the inclination angle ⁇ corresponds to approximately 90 °, then the evaluation unit AE recognizes that the appliance door GT is partially or completely opened. In the present case, the evaluation unit AE is set such that the program end display means AZ remain activated both with the door GT fully open and completely closed, while the program end display means AZ are to be deactivated in the intermediate positions of the appliance door GT.
  • the control device SE For the deactivation of the optical display means AZ, the control device SE generates the already mentioned switch-off signal Saus when the intermediate position of the appliance door GT is detected, with which the bistable relay RE is actuated immediately after the wash program has ended via the second signal line SL2. Then the relay RE switches the Switching member AS from the closed position to the open position, whereby the
  • Household dishwasher is completely disconnected from the mains.
  • the switching element AS of the relay RE thus acts as a main switch, which automatically disconnects the power supply NT of the domestic dishwasher from the power supply network after completion of the wash program. In this way it is achieved that after the
  • End of the program in particular a power supply via the power supply NT is interrupted to the optical display means AZ of the power indicator BA. Therefore, it takes place after the end of the program only as long as an energy-consuming optical display, until the user opens the door GT.
  • the microswitch ES is in signal connection via an input line EL directly to the control device SE.
  • the voltage pulse provided by a manual pressure actuation of the microswitch ES is therefore also conducted directly to the control device SE, which detects and evaluates the pulse.
  • the control device SE Upon detection of such a voltage pulse, the control device SE checks whether the power supply NT is already activated during the pressure actuation of the microswitch ES. When not activated, power supply PS, the controller SE detects a turning-on operation of the user, and controls, as described above, with the switch-S on the relay RE to. When already activated power supply NT recognizes the controller SE in the micro-switch pressure actuation a switch off operation of the user, so that the control device SE a corresponding switch-off signal S out to the relay RE. In this case, the household dishwasher is put out of action. An optionally currently running wash program is thus interrupted.
