Definitions

  • the invention relates to an electric shaver with a built-in battery for power supply and with a measuring device and an electrically connected capacity indicator for the capacity or charge status of the battery.
  • a shaver is state of the art.
  • Shavers are also already known, in which entire numerical conductors are attached and corresponding percentages are identified by illuminated markings. However, such devices are difficult to integrate into a modern device design.
  • the Capacity display clearly shows the user the capacity status of the power supply cells and indicates the need for recharging or a cell change.
  • the capacity display of such a shaver should also be easy to integrate into the design of a modern device housing.
  • the shaver has an electric clock in addition to the measuring device, which serves to display the time and to control the charging process and that the measuring device and the clock are electrically connected to a digital display panel , which is provided for the optional display of the time and the state of charge.
  • Such a digital display field shows the capacity or charge status of the power supply cells practically unmistakably in a numerical value.
  • a digital display panel can also be made relatively small, for example, so that it can be easily integrated into the design of a modern device housing. With the help of the electronic clock connected to the digital display panel, it is also easy to monitor the time while shaving. You always have the time on the shaver right in front of you.
  • Such an embodiment is also only associated with comparatively little effort, since a number of electrical components, including the digital display panel, are present in the electric shaver according to the invention anyway.
  • the clock of the razor according to the invention can also be used to control the charging process of the accumulators in addition to displaying the time.
  • the loading process can be thus control in time, with a certain time for charging being predefined.
  • This time specification can be matched to the intended charging current of the batteries, so that overcharging which is harmful to the batteries is avoided. This also gives you the option of working with a significantly higher charging current and thus a shorter charging time. This is of major advantage for practical operation. Without a charge limit, it is necessary to set the charging current to a comparatively low value so that the batteries are not damaged during continuous charging. This is avoided when the charging time is limited, as is provided in the shaving apparatus according to the invention.
  • the digital display field is expediently designed as a liquid crystal display.
  • a liquid crystal display can still be read well even with relatively small dimensions.
  • the measuring device uses the digital display panel to indicate the respective capacity or charge status of the power supply cells in percent, 100% of the capacity or charge state corresponds to the charged or not yet discharged power supply cells.
  • An embodiment is preferred in which the measuring device indicates the respective capacity or charge state of the power supply cells as a percentage in increments of ten (100%, 90%, 80%, etc.) via the digital display panel.
  • the ease of use and readability of the capacity display of the shaving apparatus according to the invention is further favored if the display field is designed as a flashing signal for charging the battery.
  • the capacity display is designed according to the invention as a digital display field 2.
  • the digital display field 2 clearly shows the capacity status of the power supply cells, which are also arranged inside the housing and are not visible here, in the form of a numerical display, the respective capacity or charge status in percent, preferably in increments of ten (100%, 90%, 80%, etc .) is specified.
  • the numerical display "100%" shown in FIG. 1 corresponds to the capacity or charge status of the charged or not yet discharged power supply cells.
  • the shaving apparatus shown in FIG. 1 carries a shaving foil 5 on the upper, removable housing part 2 of its housing 4. Below the shaving foil, the long-hair cutter 6 is provided on one of the two broad sides of the housing 4 of the shaving apparatus 1. In the lower edge region or end region of the housing 4 in FIG. 1 facing away from the shaving foil 5, the digital display field 2 is also clearly visible on the same broad side. Despite its comparatively small dimensions and correspondingly easy to integrate into the housing 4, the digital display field 2, which is designed as a liquid crystal display, can also be clearly read by the user.
  • FIGS. 2 and 3 show the electric shaver 1 from FIG. 1 with different displays of the capacity state of its power supply cells on the digital display panel 2. While in FIG. 2 the digital display panel 2 shows that the power supply cells are compared to their charged or 3, the digital display panel 2 is shown with a display value "20", which corresponds to a residual charge state of approximately 20%. This value is expediently to be regarded as the lower minimum in order to have a certain residual reserve in the power supply cells.
  • This state shown in FIG. 3 can optionally also be signaled by a "flashing" of the numerical value if the display field 2 is designed as a flashing signal for charging the battery or the state of charge of the battery (s).
  • the display on the digital display panel is only in “operation” when the device and its shaving head drive are switched on via switch 7.
  • FIG. 4 shows a perspective side view of the shaving apparatus 1 from FIGS. 1 to 3, which has an electronic watch (not visible here) in the interior of its housing 4, which is also connected to the digital display field of the electric shaving apparatus 1 for time display .
  • the electronic clock built into the shaver 1 allows ongoing time monitoring even during shaving, for example to meet an appointment or other obligation as punctually as possible.
  • the time display "1:40 pm" is shown on the digital display panel.
  • the time could be displayed on the digital display panel 2, for example in the "idle state" of the electric shaver 1, while the switch 7 automatically switches to "capacity display” when the device is switched on.
  • one control button 8 is provided for the display "clock” and one control button 9 for the display of the capacity.
  • an embodiment (not shown here) according to the invention also provides that a selection switch is provided for the display on the digital display panel, and that when this selection switch is actuated, the time display on the digital display panel of the capacity state and vice versa.
  • the watch can also be used to control the charging process of the batteries.
  • the charging process can thus be timed, with a specific time for charging being predefined.
  • This time specification can be matched to the intended charging current of the batteries, so that they are harmful to the batteries Overloading is avoided. This also gives you the option of working with a significantly higher charging current and thus a shorter charging time. This is of major advantage for practical operation. Without a charge limit, it is necessary to set the position current to a comparatively low value in order not to damage the batteries during long-term charging. This is avoided if the time limit is limited. If necessary, a measuring circuit for the charge or discharge status of the batteries can also be provided, which permits an even more precise control of the charging time.
