  • This enables a particularly inexpensive construction.
  • special operating mode the household cooking appliance is able to operate the radiators by means of a simple and inexpensive electronic circuit via a corresponding control of the heating circuit relay as part of a temperature control.
  • the heating circuit relay can consequently be switched on and off, in particular clocked, by means of the electronic circuit during operation or during the special operating mode.
  • the electronic unit can be kept simple, since functionalities such as temperature setting and temperature measurement for simple operating modes are already covered by the very inexpensive mechanical control element (mechanical temperature controller).
  • Such a household cooking device is only slightly more expensive than a purely mechanically controlled cooking device, but considerably cheaper than a purely electronically controlled cooking device.
  • a further advantage results from the fact that now automatically running cooking programs ("automatic programs”) can be offered with different target cooking chamber temperatures, as a result of which a variety of the automatic programs and consequently a variance of the dishes which can be treated with them are significantly increased.

  • a cooking result is not or only slightly changed by the temperature reduction. Possibly. may extend the cooking time.
  • This special operating mode can be regarded as a "hybrid" operating mode, since it has a conventional operating section which regulates the temperature by means of the temperature controller and an operating section which regulates the temperature by means of the electronic circuit.
  • Switching on and switching off an electrical consumer, for example a radiator means in particular that the operating mode selector switch switches a circuit belonging to the electrical consumer during operation of the set one Operating mode can be closed (which means that this consumer can be energized) or is permanently open (which means that this consumer cannot be energized). In the switched-off state, the associated electrical consumer cannot be operated.
  • the mode selector switch is a mechanically switching mode selector switch. It can be set up to open or close at least one associated electrical contact as a function of the selected or actuated position and thus the operating mode by means of a manual actuation. In particular, by opening or closing the at least one contact, at least one heating element can be switched on for operation under the set operating mode.

If the temperature at the mechanical temperature controller is below the set target temperature, the mechanical temperature controller is closed and current can flow through the (connected) radiators.

  • the electronic circuit can recognize which selection and / or input has been made on the input device.
  • the input device can also be used for other inputs or displays, for example a cooking time.

This ensures that when an automatic program runs, the circuit of the at least one radiator for temperature control is closed and opened only by means of the heating circuit relay, regardless of a setting of the mechanical temperature controller. In a manual operating mode, the mechanical temperature controller is not electrically bridged.

  • the rotary selector switch 8 is also designed and arranged such that it has a connection between the main relay 7 and the capillary tube regulator 9, between the temperature limiter 6 and the neutral conductor N, between the radiators 2 to 5 and the heating circuit regulator 10, between the radiators 2 to 5 and the clock circuit 11, between the radiators 2 to 5 and a circulating air motor 16 and between the circulating air motor 16 and the neutral conductor N can optionally close and open. All of these connections can be individually closed or opened depending on the selected rotational position. In an off or zero position in which no operating mode is selected, the rotary selector switch 8 can be set up in such a way that all connections are open.
  • the individual switches Sn can, for example, by means of a suitable, e.g. connected with a rotary knob, shaft can be operated.
  • any, but fixed, combination of the closed states (open / closed) of the individual switches Sn can be assigned to each selected position of the rotary selector switch 8.
  • the individual switches S1 to S9 can comprise, for example: a single switch S1 between the capillary tube regulator 9 and the heating relay 7, a single switch S2 between the first grill heater 2 and the heating circuit relay 10, a single switch S3 between the second grill heater 3 and the heating circuit relay 10, a single switch S4 between the lower heat radiator 4 and the heating circuit relay 10, a single switch S5 between the circulating air heater 5 and the heating circuit relay 10, a single switch S6 between the neutral conductor N and the temperature limiter 6, a single switch S7 between the single switches S2 to S5 and a signal input of the clock circuit 11, a single switch S8 between the single switch S6 and the circulating air motor 16 and a single switch S9 between the single switches S2 to S5 and the circulating air motor 16.
  • the clock circuit 11 can recognize the off position of the rotary selector switch 8 by means of a corresponding bit code, for example “000”.
  • auxiliary consumers are connected between the outer conductor L and the neutral conductor N.
  • an oven lamp 17 which is connected on the one hand between the rotary selector switch 8 and the capillary tube regulator 9 and on the other hand between the temperature limiter 6 and the individual switch S6.
  • An oven operating indicator lamp 18 is connected in parallel with the oven lamp 17.
  • a cooling fan motor 19 is connected on the one hand directly to the neutral conductor N and on the other hand is connected between the rotary selector switch 8 and the main relay 7. All of the consumers 2 to 5 and 16 to 19 described except for the clock circuit 11 are therefore electrically connected in series with the main relay 7, so that when the main relay 7 is open, these consumers 2 to 5 and 16 to 19 are not supplied with electrical energy and are consequently switched off are.
  • a user turns the rotary selector switch 8 from its off or zero position to a rotary position which corresponds to an operating mode desired by the user.
  • the operating mode can be a "manual" operating mode which is usual for ovens with mechanical oven regulators (e.g. capillary tube regulators 9), such as a grill mode, a bottom heat and / or top heat mode or a recirculation mode.
  • the heating circuit relay 10 which can be controlled on the clock circuit 11 also enables operation with special operating modes such as at least one automatic operating mode, energy-saving cooking (for example an "energy-saving mode") etc.
  • the heating circuit relay 10 is not required and is in the process of manual Operating mode permanently closed.
  • the rotary selector switch 8 closes the individual switch S1 between the capillary tube controller 9 and the heating relay 7, the individual switch S6 between the neutral conductor N and the temperature limiter 6 and the individual switches S2 and S3 between the grill radiators 2 and 3 and the heating circuit relay 10.
  • the individual switch S7 between the grill radiators 2 and 3 and the clock circuit 11 will be closed, so that the clock circuit 11 receives feedback that at least one the radiator 2 to 5 can be supplied with electrical energy or is switched on.
  • a corresponding bit code can now be read from the clock circuit 11 on the rotary selector switch 8 or a corresponding bit code is now output by the rotary selector switch 8 to the clock circuit 11.
  • the clock circuit 11 processes the bit code (e.g. by means of a corresponding processing device) and subsequently closes the heating circuit relay 10 or leaves it closed. This also creates an electrical connection between the grill element 2 and the capillary tube regulator 9, so that the grill element 2 is now connected both to the outer conductor L and to the neutral conductor N and can therefore be supplied with electrical energy.
  • the associated temperature control takes place, as usual, by setting the temperature on the capillary tube regulator 9.
  • a time-shifted and / or a time-limited operation of the grill mode can also be set, e.g. starting in one hour after activation with a duration of two hours.
  • the clock circuit 11 opens and closes the main relay 7 accordingly.
  • the switch S5 can be closed instead of the switches S2 and S3 in order to operate only the air circulation heater 5.
  • the switch S9 can be closed in order to also operate the circulating air motor 16.
  • the capillary tube regulator 9 may not be suitable for the special operating modes, because different temperatures are to be adjusted depending on the preselection.
  • a special operating mode is selected on the rotary selector switch 8, e.g. "Automatic mode", similar to the selection of a previously usual manual operating mode, the appropriate at least one radiator from the group of radiators 2 to 5 is switched on by closing the corresponding individual switches S2 to S5, and possibly also the air-circulation motor 16.
  • a user when selecting "automatic mode", a user is asked to select a specific automatic program from a group of possible automatic programs via an input device 25.
  • the input device 25 is connected to the clock circuit 11, so that inputs on the input device 25 can be recognized and / or processed by the clock circuit 11.
  • the specific automatic program After selection of the specific automatic program, the user is asked to enter a weight or a weight range of the food to be treated or the food to be treated on the input device 25.
  • the heating circuit relay 10 is then controlled by the clock circuit 11 so that the cooking space temperature is regulated in an associated cooking space or oven space of the oven 1.
  • the clock circuit 11 can switch the heating circuit relay 10 on and off in accordance with a predetermined control algorithm.
  • a particularly simple control algorithm can consist in opening the heating circuit relay 10 when the (actual) cooking chamber temperature sensed by the temperature sensor 20 has reached or exceeded the target cooking chamber temperature and then when the actual cooking chamber temperature has reached the target cooking chamber temperature has reached or fallen below.
  • the capillary tube regulator 9 can be set by a user to a temperature value (at which the capillary tube regulator 9 opens or interrupts) which is above a temperature value that can typically be achieved in the selected automatic operating mode, for example to a maximum adjustable temperature value.
  • the operating parameters suitable for the selected special operating mode e.g. a target cooking space temperature, a cooking time, a resting time and / or their change over time, etc.
  • the heating circuit relay 10 When a special operating mode is selected, the heating circuit relay 10 is actuated in a clocked manner by the clock circuit 11, so that the suitable radiators 2 to 5 are also switched, in particular clocked, during operation. It takes place in one Variant does not regulate the temperature in an associated cooking space or oven space of the oven 1 instead, for example in that a cycle (for example a period, a duty cycle, etc.) is not dependent on an oven temperature in the oven space.
  • the capillary tube regulator 9 can be set by a user to a temperature value (at which the capillary tube regulator 9 opens or interrupts) which is above a temperature value that can typically be achieved in the selected special operating mode, for example to a maximum adjustable temperature value.
  • the clock circuit 11 can determine or define the clocking parameters (period, duty cycle, etc.) suitable for the selected special operating mode on the basis of the bit code transmitted or read out by the rotary selector switch 8.
  • the oven 1 can carry out at least one operating mode (in particular an operating mode which is customary for this) by means of mechanical-thermal control via the mechanically adjustable rotary selector switch 8 and the capillary tube regulator 9 and can carry out an electronically controlled heating operation in a simple and particularly inexpensive manner in at least one automatic operating mode.
  • the operating mode can also be a hybrid operating mode.
  • the electronic unit designed here as a clock circuit 11 can be kept particularly simple, since basic functionalities (temperature setting, temperature measurement and control), in particular for conventional operating modes, are already covered by the very inexpensive mechanical control element (e.g. the capillary tube regulator 9).
  • the integration of such a simple “electronic temperature measurement” means that a cooling fan or the associated cooling air motor 19 can be controlled as a function of the cooking space temperature by means of the clock circuit 11.
  • the clock circuit 11 can also be set up to implement temperature-based door opening detection.
  • the clock circuit 11 can be set up to reduce the cooking space temperature on the device side as a function of the electronically measured cooking space temperature, in particular in the context of "hybrid" operation.
  • Fig. 2 shows a second circuit 21 of a second oven B2.
  • the circuit 21 differs from the circuit 1 in that the main relay 7 is missing, but there is a further relay (“secondary consumer relay” 22) on a clock circuit 23.
  • the secondary consumer relay 22 is electrically connected in series with the secondary consumers 16, 18 and 19, so that these can advantageously also be operated when the radiators 2 to 5 are switched off by continuously opening the heating circuit relay 10.
  • the cooling air motor 19 can now be operated independently of the other consumers through the baking oven B2, for example in order to enable a vapor extraction and / or a cooling air supply to continue to run.
  • an LED can also be used in the circuit 1 instead of the oven lamp 17.
  • the capillary tube regulator 9 can be bridged in a non-manual operating mode such as an automatic operating mode.
  • a number can also include the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
