Definitions

  • the present invention relates to an arrangement for controlling cookers for heating and cooking food and liquids with microwave energy and / or thermal energy by means of resistance heating using a time and / or program control device by means of which the microwave energy can be adjusted with respect to heating power by clocking and with regard to heating duration is.
  • microwave ovens it is also known for microwave ovens to provide control measures which control the heating power by clocking the microwave power within a limited period of time that can be preset immediately after a start command has been entered.
  • control measures which control the heating power by clocking the microwave power within a limited period of time that can be preset immediately after a start command has been entered.
  • the maximum time allowed for a microwave cooking process is fixed in any case and cannot be exceeded.
  • microwave-only operation and pure heating operation can be time-controlled in the manner described using the resistance heating elements.
  • An arrangement which meets these requirements is characterized according to the invention in that switching measures of the time and / or program control Unit are assigned that the resistance heating according to set temperature and / or energy values for the duration of the microwave operation are supplied to the food.
  • the arrangement according to the invention is characterized in that a selector switch is assigned to the time and / or program control device, via which this program control device can alternatively be set to the time-controlled operating modes "microwave", “time-controlled resistance heating” and “microwave resistance heating combination ". If this selector switch takes the "microwave” position, the resistance heating can be switched on and off manually, regardless of whether microwave operation is taking place or not. This microwave mode is set via input elements of the time and / or program control device.
  • the operating mode selector switch 1 is used to enter the operating modes, in each case one switching position is provided for the operating modes "time-controlled resistance heating", "microwave” and "time-controlled microwave-resistance heating combination”.
  • the microwave operation can be preset and started by entering microwave power values via the corresponding buttons 2 of the control unit and time values assigned to this control unit via a rotary switch 3, which are shown on the display 4, and after that - prompted the indicator light 5 in the start button 6 is actuated by the flashing.
  • Microwave operation must be ended prematurely by pressing a stop button 7.
  • a temperature selector switch 8 is used to set the operating values, which, in addition to the position for the oven lighting, can be set to temperature values between 50 ° C. and 250 ° C. and for a grill operation.
  • the resistance heating is to be carried out in a time-controlled manner, a setting is to be made in the same way via the temperature selector switch 8, but the selector switch 1 for the operating modes is to be set to the "time-controlled resistance heating" position. It is now indicated by flashing that an assigned key 2 is to be pressed and the time must be entered via the rotary switch 3. Then the time-controlled resistance heating is started by pressing the start button 6.
  • the setting values can be entered as in the case of pure microwave mode and pure resistance heating mode, the setting times for microwave mode being automatically adopted for resistance heating mode.
  • the cooking process is also started using the start button 6.
  • the different operating modes which can be carried out with the aid of the cooker equipped according to the invention, are realized as binary values by the positions of the switches F1, F2, F3, which can be set by cams of the selector switch 1, which the function control device ZSt be forwarded.
  • the illustration shows that when the operating mode with thermal heating is used, the switches F1 and F3 are kept open when the operating mode with microwave heating is used. If both types of heating are used in a superimposed manner, all three switches F1, F2, F3 are consequently kept open.
  • Fig. 4 shows that the switch F1 is connected to the heating circuit for the heating resistors R1, R2, R3.
  • the switches F2 and F3 are used to enter information for the control device ZSt.
  • the heating resistor R1 serves as a grill heater and as a heater for the top heat, while the heating resistors R2 and R3 are assigned to the bottom heat in the oven.
  • the temperature controller TR in the power circuit is set to the operating value by the temperature selection switch 8 (FIG. 1). Further cams are arranged on the shaft of the temperature selector switch, via which the switches T1, T2, T3, T4 can be switched. The switches T1 and T2 are closed when the temperature selection switch 8 is rotated in the area in which the heating is to take place.
  • the switch T2 In the temperature range up to 250 ° C, the switch T2 remains closed and the switch T3 is open, so that the heating resistors R2 and R3 are available to provide the bottom heat and the heating resistor R1 - due to the series connection with the heating resistor R3 - supplies the top heat. If the temperature selection switch 8 is turned to the grill position, the switch T2 opens and the switch T3 closes. This means that the heating resistors R2 and R3 are deactivated and the heating resistor R1 is now at the full supply voltage in the function as a grill radiator. The control range of the temperature controller TR is also exhausted, so that the assigned switch remains closed. Depending on the rotary setting of the temperature selector switch 8 in the grill area, an energy acts Regulator ER for clocking the heating current for the heating resistor R1 to reduce power.
  • the operating mode selector switch 1 is set counterclockwise to the "thermal heating" operating mode.
  • the switch contacts F1, F2, F3 are actuated by cams arranged on the shaft of the operating mode selector switch 1 in such a way that the switch contact F1 and the switch contact F3 open and the switch contact F2 closes.
  • the power supply to the heating elements via the switch contact F1 is thus interrupted.
  • a relay R11, which closes the relay switch Sr1, is excited via the time / program control device ZSt during the predetermined time period, so that the heating current is conducted via this relay switch Sr1.
  • relays R12, R13, R14 which can be influenced by the time / program control device ZSt are used via the assigned relay switches Sr2, Sr3, Sr4 to control the microwave generator with the magnetron Mg.
  • This microwave generator can generally only be operated via the time / program control device ZSt.
  • the contacts e1, e2, e3 serve to secure the door during microwave operation.
  • Fig. 4 shows the time / program control device ZSt in connection with the input elements.
  • the central unit of this time / program control device is a microprocessor ⁇ P (eg KS5 100 from Tristar), whose inputs K1, K2, K3, K4 both through the switch contacts L3 of the keys 2 (according to FIG. 1) and through switch contacts F2, F3 e1, S6, S7 are multiplexed via the outputs R1, R0 and R3.
  • the relays R11, R12, R13, R14, of which only the relay R11 is shown in the figure, are controlled via the outputs R8 to R10.
  • the relay R11 is - as can be seen in particular from FIG.
  • the relay R14 is energized during the predetermined period in microwave operation and keeps the associated relay switch Sr4 closed. Via the relays R12 and R13 and the assigned relay switches Sr2 and Sr3 the microwave device is powered.
  • the display arrangement (for example 4-LT-13 from Futaba), which is controlled in a known manner by the outputs R0 to R6 and 00 to 07 of the microprocessor uP, is arranged to display time and operating data as well as operating states.
  • switches S6 and S7 are assigned to start button 6 and stop button 7, respectively.
  • the necessary device for the power supply is not shown and described, since it is not essential to the invention and can be constructed in a generally known manner.
  • the clock pulse T is generated in a known manner from the operating alternating current.
