Definitions

  • the invention relates to an electromechanical stove timer with a Motor-driven analog display of the time and displays for cooking time and start of cooking time with Devices for setting the time and the operating times as well as with a or several relays for switching the stove functions.
  • a stove timer is known from DE-OS 1908042.
  • stove time switches were built purely electromechanically or in more recently, purely electronically. To this day, they have become electromechanical built-up stove timers kept on the market for price reasons, electronic Stove time switches have the main advantage that the realizable with them Functions are more diverse and are cheaper to implement than mechanical trained functions.
  • DE-OS 1950615 discloses an electromechanical stove timer, one driven by a synchronous motor Electromechanical stove timer is operated, with a usual time display with hands, a single hand for the end of the cooking time and a falling leaf display in digital form for the cooking time.
  • this is achieved in a watch of the type mentioned at the outset by that said devices from one or more function selection switches 5 for time, cooking time and start of cooking time and one or more There are operating switches 16, 24 for setting the time and the operating times, that an electronic control device 23 for controlling the adjustment of Analog displays 2,3; 13,14, cooking time and start of cooking time is present and that the time
  • an electronic memory 23a for the Storage of at least the cooking time is provided and that the setting of the beginning of the cooking time through motorized adjustment of the clock hands 2,3; 13,14 with simultaneous storage the time difference from the current time in a further electronic memory 23b he follows.
  • the cooking time can be displayed either by a Digital display or through a one-hand analog display in the time field or outside be educated.
  • the display can deviate from the prior art the beginning of the cooking time by two hands, preferably by the hands of the time.
  • the special feature of the proposed stove timer is that both the adjustment of the analog Time display, the mechanical start time setting as well as the electronic one stored cooking time and the electronic storage of the time difference between current time and start of cooking time by the electronic control device output clock pulses takes place.
  • FIG 1 is the front of an analog electromechanical stove timer shown with a dial 1, two clock hands rotating in the usual way 2 and 3, an additional digital display 4 with three digits and one as Multi-function switch 5 trained function selection switch, which by turning from the so-called manual position "I” to a functional position "clock”, in one position cooking time start "KB", one position cooking time “D” and one Short-term position “KZ” is rotatable. By pushing this switch in the respective selected functional position is adjusted will. The adjustment is made as long as the switch is pressed is due to electrical impulses from the built-in electronic control device.
  • the arrangement of the digital display and the function selection switch can of course also occur elsewhere on the front of the watch than in the drawing shown.
  • the function selection switch 5 it is also possible to provide several function keys and the setting function each on one Key or in a central operating switch for all functions to provide. In the sense of the invention, this configuration is the functional elements not of importance.
  • the front is in a second embodiment of the invention an electromechanical stove timer shown with a first dial 11, a second dial 12, usual time hands 13 and 14, another Pointer 15 for setting the cooking time and a function selection switch 16 with basically the same structure as in FIG. 1.
  • FIG 3 is the basic structure of the stove timer in a block diagram shown.
  • a circuit board 20 On a circuit board 20 is a key decoder 21, a function decoding 22 and an electronic control device 23 are arranged.
  • This contains, preferably in a microprocessor, an electronic memory 23a for storing the cooking time and an electronic memory 23b for Storage of the difference time when entering a cooking time start.
  • buttons 24 On the electronic Several buttons 24 are arranged schematically at the input of the printed circuit board 20, via which the functions and the adjustment signals are entered.
  • a terminal 25 On a terminal 25 is the mains power supply.
  • 28 denotes a digital display with three digits, which is preferably is realized with LEDs. Instead of three digits would be in the spirit of the invention also a representation with only 2 1 ⁇ 2 digits is possible, as long as no longer with the clock Cooking time, pyrolysis or short time are displayed as 199 minutes should.
  • 21a shows a DCF 77 receiver for receiving the radio time signal. The clock can optionally be equipped with it so that the time is automatic is provided. 21a acts on the control unit via the function decoder 22 23.
  • an analog display with a pointer 15, as shown in Figure 2 can be provided.
  • the control of the motorized adjustment this pointer 15 takes place with pulses.
  • this second pointer 15 is preferably a second drive motor would be provided, in the sense of the invention however, it is also possible to switch the stepper motor for the time display of a transmission can also be used for the adjustment of this pointer.
  • the pointer 15 has a position 0 and a position I.
  • the position 0 is the normal position, from which the pointer is adjusted when the cooking time is set. When the cooking time has elapsed, it returns to this position 0. Actuated he a signal contact, not shown in the drawing, which defines this position. If the function selector switch is in position I, ie in the "manual" position adjusted, the pointer 15 from the drive motor to the left in the position I adjusts and thus visually indicates manual operation.
  • This watch works as follows. The time is initially changed set that the function selector switch 5 rotates to the "clock” position and is then pressed.
  • the electronic control device 23 gives impulses to the motor 26, which gradually adjusts the clock hands, initially slowly, after 10 steps with a significantly increased speed. Once the current When the time is reached, the function selector switch 5 is released, the adjustment the clock hand is finished, these now run at timed speed continue.
  • the function selector switch 5 is set to the "I" position. This is the position for "manual" operation.
  • the function selector switch 5 is set to the "D" position. In this position, pressing the function selector switch in the Memory 23a the desired cooking time entered and shown on the display 4 will. In this case, the cooking or baking process takes place immediately, i.e. more specifically, about four seconds after you finish entering the cooking time. This can be seen from the pulse diagram in FIG. 4. One speaks in one in such cases also from an immediate operation of the stove timer. From the electronic Control device 23 outputs pulses to the memory 23a, which count this down until the counter reading "0" is reached.
  • the stove timer is to be operated in automatic mode, either first by setting the function selector switch 5 accordingly Cooking time and then a cooking start time can be entered or vice versa. In both cases, the function selector switch must first in one and then in the other position and by pressing the display in the desired position Way to be adjusted.
  • a cooking time is to be entered first, this process goes into in the same way as described with reference to Figure 4. Then will the function selector switch 5 is set to the "KB" position and by pressing the Switch the time hands 2 and 3 to the desired time later Cooking start time adjusted. For example, this may be two hours later than the one in Figure 1 current time shown 9 o'clock. The adjustment of the time hand takes place, first slowly, then quickly, as long as the function selector switch 5 is pressed. This switch must be released when the hand is at 11 o'clock will. The time hands remain in this position until the current one Time has reached the start of the cooking time.
  • the Adjustment pulses are not only given to the motor 26, but also to an electronic one Memory 23b in the electronic control device 23, the one Memory status of 120, corresponding to a difference of 120 minutes.
  • This The electronic control device stores memory every minute - already starting with the entry of the cooking start time - counting down until it reaches the counter reading Has reached "0". From this point on, impulses from the electronic control device 23 to the motor 26 for time-keeping, normal Adjustment of the clock hands 2 and 3 is given.
  • the electronic Control device of the memory 23a and its content likewise every minute, counted down and "cooked" the cooking time. At the This decrease in cooking time can be read off display 4.
  • the relay 27 Simultaneously with the beginning the cooking time is the relay 27, which begins with the start of the cooking start time first closed and then opened again, again closed and now begins to supply energy to the stove. After completion a buzzer signal sounds again during the cooking time.
  • FIG. 6 shows a pulse diagram which shows the function of the stove timer when entering the start of the cooking time and then the cooking time explained.
  • a short time is stored and displayed according to FIG. 7, after corresponding setting of the function selector switch 5 to the "KZ" position, via the electronic memory 23a and the display 4 in the same way as in Enter a cooking time.
  • the relay itself is not activated.
  • a pyrolysis function can also be provided will.
  • the pyrolysis time is entered, saved and displayed in the same way Like a cooking time.
  • the only difference is that when setting the function selector switch 5 of the stove in the pyrolysis position for this Function, a time suggestion of, for example, 90 minutes appears in the display 4, which, however, can be corrected by the user.
  • the function selector switch of the Heard acts on the key decoder 21.
  • the electronic memory 23a is sufficiently dimensioned to be consecutive Inputs, such as cooking time, short time and pyrolysis, accordingly to be able to save.
  • the storage content is processed by Appropriate selection of the function selector switch 5.
