Definitions

  • the invention relates to an electric shaver with a shaving foil and a shaving head interacting with the shaving foil according to the preambles of claims 1 and 2.
  • Such a shaver is known from JP-A-3 218 791.
  • the shaving foil can adapt to the contour of the surface to be shaved and the shaving head knife.
  • a generic shaver has become known, in which a display device is connected to an operating time counter for making a recommendation to change the film.
  • An operating time count on the basis of an autonomous oscillator, for example a clock component customary on the market, allows the operating time to be determined as a function of the on / off switch of the shaving apparatus and thus only a relatively rough estimate of the actual wear of the shaving foil.
  • the wear to which the shaving foil is subjected depends on the friction between the shaving foil and the blade block which is moved in a form-fitting manner relative to the shaving foil.
  • the foil now adapts to the contour of the face to be shaved and the contour of the shaving head, which means that the wear also significantly depends on the load or from the respective user guidance.
  • the invention now aims to provide an electric shaver of the type mentioned at the outset, which is intended to ensure an improved estimate of the actual wear of the shaving foil and can give a corresponding recommendation for changing the shaving foil in order to substantially reduce the risk of injury to the user of the shaving apparatus.
  • the shaving apparatus of the type mentioned at the outset essentially consists in the display device being connected to a device for detecting the load on the shaving foil and an evaluation circuit.
  • an improvement can be achieved in that the display device is connected to an operating time counter triggered by the clocking of the motor and an evaluation circuit.
  • Such a display device when it displays a corresponding signal, makes a foil change recommendation to the user and thus ensures that excessively worn shaving blades are no longer used. It is not readily possible for the user of a shaving apparatus to recognize the correct point in time at which a shaving foil is to be changed, since a defective shaving foil is primarily recognized by the injuries already occurring. With such a display device, the point in time at which injuries could occur is now recorded Safety is displayed prematurely and the possibility is created to change a shaving foil before an injury becomes possible.
  • an improved estimate of the actual wear of the shaving foil is obtained if the operation of the display device also includes an evaluation of other operating parameters, for example the power consumption or the like.
  • the operating time count is therefore advantageously combined with a device for detecting the load on the shaving foil and an evaluation circuit, such a device for detecting the load on the shaving foil and an evaluation circuit also being able to provide correct information for triggering the display device independently of a pure operating time count.
  • the design according to the invention can be made such that the operating time counter is triggered by the clocking of the motor, with such a combination of the time counting and the clocking of the motor making a combined statement about the load on the shaving foil possible.
  • the design according to the invention is such that the device for detecting the load on the shaving foil is formed by a current consumption measuring device, the measured values of which are connected to the display device via an evaluation circuit, in particular an integrator.
  • the integrated power consumption gives the possibility to issue a shaving foil recommendation regardless of the time actually elapsed, whereby the integration of the power consumption naturally takes place via the power consumption in the time unit.
  • the design according to the invention can be such that the device for detecting the load on the shaving foil comprises pressure sensors which interact with the shaving foil, such a detection of Pressure readings also take into account the most common operator errors when using the electric shaver.
  • Such a display device with which reference is made to the necessary film change, can in turn be deleted in different ways.
  • the design is advantageously such that the display device can be erased via a switch contact which resets the counter, the switch contact preferably being mechanically coupled to the shaving foil and being automatically operable when the shaving foil is changed.
  • the switching contact is mechanically coupled to the shaving foil, a reset and deletion is effected immediately after changing the shaving foil.
  • the training can be carried out in a particularly simple manner in such a way that the counting or evaluation circuit connected to the display device has a flip-flop that can be set and reset, which can be set by the counting or evaluation circuit and reset by a switch contact, which also Finding it with the least amount of electronic effort.
  • FIG. 1 shows a first embodiment of the circuit arrangement with a simple counting device
  • FIG. 2 shows a schematic representation of the combination of the evaluation of engine timing and oscillator signals.
  • the engine timing is indicated schematically by 1 in FIG.
  • the engine clock or a clock signal is fed to a time counter 2, the output signals being fed to the display device 4 via a resettable flip-flop 3.
  • An external switch contact, schematically indicated by 5, is connected to the resettable flip-flop 3, which causes the flip-flop and thus the indicator or the display device 4 to be reset.
  • the display device 4 can be formed by an LED or a corresponding symbol of an LCD.
  • the time count in the formation of a FIG. 1 can be such that, for example, the corresponding indicator 4 is displayed after 30 or 35 operating hours.
  • the engine timing is indicated schematically in FIG.
  • the pulse shape of the oscillator signals is shown schematically at 7.
  • the signals existing in parallel in this way are fed to an AND module 8 and subsequently evaluated in a counter 9.
  • the connection of the engine timing with the oscillator also shows the load state in this way and only the signals linked in this way are the counter 9 and subsequently the flip-flop 3 or the indicator 4, as they were shown in Fig.1 , fed.
  • the oscillator frequency is selected to be significantly higher than the clock frequency of the motor.
