Definitions

the invention relates to an electronic watch with a; Solar cell arrangement, with a memory for that of. electrical energy supplied to the solar cell arrangement, with a clock connected to the memory. circuit and with a display device.
the invention has for its object to provide an electronic clock of the type mentioned, which is characterized by a high power reserve.
This object is achieved in that the display device for direct power supply is connected directly to the solar cell arrangement.
the fact that the power supply is separated from the watch electronics and the display results in substantial energy savings and thus a higher power reserve.
the display device which has the greatest energy requirement in particular in the case of larger clocks, is operated directly via the solar cells of the solar cell arrangement without any intermediate storage. This ensures that the display device is only in operation if the lighting is also sufficient for reading it.
the clock circuit is operated with an energy store, either a battery or a capacitor, which ensures that the time function is retained.
an energy store either a battery or a capacitor, which ensures that the time function is retained.
a mechanical pointer mechanism can also be used.
a stepper motor is provided which is controlled in such a way that, after it has come to a standstill overnight, it brings the pointers of the pointer mechanism into the correct position when illuminated.
the watch can also be equipped with an electronic calendar.
the solar cell arrangement is used exclusively for feeding the display device and not for recharging the battery.
the electronic clock shown in Fig. 1 has. via a quartz oscillator 1, which serves as a frequency reference for a clock circuit 2, by means of which the time keeping function of the electronic clock is ensured.
the clock circuit 2 are assigned actuation switches, not shown in the drawing, which allow the clock circuit 2 to be set to a specific time, a specific date, a specific day of the week, a wake-up time or the like.
actuation switches not shown in the drawing, which allow the clock circuit 2 to be set to a specific time, a specific date, a specific day of the week, a wake-up time or the like.
components for stopwatch functions that may be present and acoustic displays for a time and / or alarm times are also not shown. It is self-evident to the person skilled in the art that the clock circuit 2 can be equipped with such additional circuits or functions.
the clock circuit 2 is connected via a line 3 to a display device, which in the embodiment shown in FIG. 1 is a liquid crystal display 4 and in the embodiment of the invention shown in FIG. 2 is a mechanical pointer mechanism 5 with pointers 10 and 11.
a stepping motor with control electronics is assigned to the mechanical pointer mechanism 5 shown schematically in FIG. 2.
the quartz oscillator 1 and the clock circuit 2 are supplied with electrical energy via an electrical memory 6.
the electrical storage 6 is preferably a: rechargeable battery or a low-voltage capacitor with a high capacity. ;
a solar cell arrangement 7 shown in FIGS. 1 and 2 is connected via lines 8 and 9 to the liquid crystal display 4 or the mechanical pointer mechanism 5 in order to supply the liquid crystal display 4 or the pointer mechanism 5 with electrical energy.
the liquid crystal display 4 or the pointer mechanism 5 is operated directly via the solar cell arrangement 7 without interposing the electrical memory 6. Since the display device has a greater energy requirement, particularly in the case of larger clocks, a substantial energy saving is achieved by disconnecting the power supply for the clock electronics and the display because the display in the form of the liquid crystal display 4 or the mechanical pointer mechanism 5 is only in operation when the lighting is on is also sufficient for reading.
the clock circuit 2 is operated with the aid of the electrical memory 6, which can be either a battery or a capacitor, ensuring that the time function of the clock circuit 2 is retained.
a diode 12 is provided in the exemplary embodiments shown in FIGS. 1 and 2.
the diode 12 is connected with its anode to the line 8 and with its cathode to the positive pole of the electrical store 6, in particular an accumulator.
This polarity ensures that for charging the memory 6 electrons from the negative pole 13 of the solar cell arrangement 7 can reach the negative pole of the electrical memory 6 and from the positive pole of the electrical memory 6 via the diode 12 to the positive pole 14 of the solar cell 7.
the electrical store 6 is charged or recharged.
the store 6 is discharged via the diode 12
the diode 12 thus causes the electrical store 6 charged by the solar cell arrangement 7 only the electronics, that is to say in particular the quartz oscillator 1 and the clock circuit 2, and that the display device, in particular the liquid crystal display 4 or the mechanical pointer mechanism 5 with a stepper motor, is fed directly from the solar cell arrangement 7 without memory.
a non-rechargeable battery is used as the energy source instead of an electrical storage 6, for example in the form of a rechargeable battery.
the solar cell arrangement 7 is used in such an electronic watch exclusively for feeding the display device, in particular the liquid crystal display 4 or the mechanical pointer mechanism 5 and not for loading the memory 6. Therefore, in the last-mentioned exemplary embodiment there is no connection between the line 8 and the non-rechargeable battery is provided so that the diode 12 is omitted.
