Definitions

  • the invention relates to an electromechanical stove timer with a motor-driven analog display of the time and displays for cooking time and cooking time start - or optionally cooking time end - with one or more function selection switches for time and at least cooking time and cooking time start and one or more actuation switches for setting the time and / or the function times as well as with one or more relays for switching the stove functions.
  • a circuit board with electrical components is arranged in a housing, which carries a preassembled clockwork with motor, gear train and pointer mechanism, and on which there is also an electronic digital display (display) for other times and at least one function selection switch and an operating switch are arranged.
  • a circuit board is provided as a support plate for the entire clock, which is not only the carrier of all electrical and electronic components, but which also serves as a carrier of a pre-assembled clockwork for driving clock hands and finally the carrier for forms an electronic digital display for displaying all times except the time and the controls.
  • a clockwork module as used in small alarm clocks is preferably used as the pre-assembled clockwork.
  • the spatial arrangement of each other can be changed in terms of their design. It is thus possible in the sense of the invention to arrange the analog display in the stove timer in the middle or in the left or in the right part of the dial covering the entire housing, the digital display and the operating elements being able to be arranged on the left or right or below or above in the housing .
  • the digital display which preferably has three digits, is arranged in a cutout in the dial.
  • the two switches for function selection and actuation are combined in a combination switch for turning and pressing.
  • the function selection switch is designed as a rotary switch with the positions for the functions time, start of cooking time, cooking time, short time and manual operation, and that the operation switch is a pressure switch which can be operated in any position of the function selection switch and the setting of the desired time information by triggering electrical pulses.
  • the time switch automatically calculates the start of the cooking time based on the cooking time entered and starts processing the program there.
  • a printed circuit board 2 is arranged in a housing 1 of an electromechanical stove timer made of plastic and fills the entire length and width of the housing.
  • An electrical clockwork 3 carries an electronic digital display 4, which is preferably designed as an LED display, and one in one, on this printed circuit board, the conductor tracks and the electrical components arranged thereon, which are located in the interior of the housing
  • Combination switch 5 arranged for housing for function selection and actuation, which, protruding from the drawing plane, has a rotary knob 6.
  • the clockwork 3 contains in a module housing a stepper motor and a conventional gear train as well as a pointer mechanism in the form of pointer axes 7 and pointers 8 plugged onto them in the usual way. These pointers 8 show a time division of that in FIG. 1, in FIGS. 2 and 3 However, the dial 9 shown shows the current time.
  • the dial 9, visible in FIG. 1, is supported on supports 10 and held with snap lugs 11.
  • the digital display 4 is located in a section of the dial 2 and is formed by 3 seven-segment displays. This three-digit display makes it possible to indicate a cooking time of up to 180 minutes or a cooking time start of up to 999 minutes or a short time if the timer is to work as a short time meter. The corresponding functioning of the watch will be discussed later.
  • the display device 4 is supported on the printed circuit board 2 via feet 12 and is electrically connected to the printed circuit board 2 by means of wires 13.
  • the circuit board itself is fixed via hooks 14 and lugs 15 in the housing.
  • the clockwork 3 is connected to the printed circuit board by means of pins 16 and hooks 17 in a rotationally secure and positive manner. At the same time, an electrical connection between the clockwork and the printed circuit board, not visible in the drawing, is ordered for the power supply and for controlling the motor.
  • the timer can be inserted in a stove top.
  • a cover glass 19 can be provided.
  • the assembly of the circuit board 2 is advantageously carried out in such a way that those electrical components that emit little heat are arranged on the inside of the housing facing side of the circuit board, whereas those components or assemblies 20, such as. B. Relay, power supply, which a lot of heat deliver, or the buzzer can be arranged on the outside of the housing facing the circuit board.
  • a circuit board with a receiver for radio time according to the DCF 77 time signal can be arranged in the housing, preferably between the clockwork and the dial. If necessary, this receiver controls the clockwork if there is no signal from the control circuit for the clockwork.
  • the mode of operation of the time switch is of minor importance here and should only be briefly touched upon.
  • the time can be set by turning the function selector switch 5 to the " time" position printed on the dial but not shown in the drawing.
  • the electronic control circuit arranged on the printed circuit board gives impulses to the motor for adjusting the pointers 8 of the clockwork 3.
  • the function selector switch is released and returned to its starting position.
  • the function selector switch 5 is turned to the correspondingly marked position and then pressed. Starting from position 000, the desired cooking time in minutes is entered on the digital display and displayed there. If the watch is not operated in any other way, the cooker starts the cooking or roasting process under the control of the cooker timer while simultaneously processing the cooking time until the digital display shows 000 again.
  • the function selector switch is turned to the "start of cooking time" position and then pressed.
  • the motor of the clockwork now receives 3 pulses and the hands of the clock start to run forward until the desired start of cooking time is reached on the analog display and the function selector switch 5 is released.
  • This difference in time between the current time and the set start of cooking time is stored electronically at the same time.
  • the stove timer provides the possibility that the clock hands are reset to the current time. However, this means that the start of the cooking time on the clock is no longer shown but only calculated internally.
  • the hands of the watch preferably remain on the selected start of the cooking time and this is processed electronically in the watch in a time-keeping manner. From the start of the cooking time, the clock hands start running again, at the same time the stove is switched on and cooked or fried according to the set cooking time.
